for 2 micro gram/ml, we take 10 micro litter from stock and than make up to 5ml which prepare 2 micro gram/ml solution. similarly all conc. we can prepare. if any drug is in solid form i.e. powder then, firstly we have to make its solution with desired solvent for exa distill water.

### How do you calculate concentration in micrograms per ml?

From molar concentration to mass concentration: The simple formula is: ( µg/mL ) = ( µM ) * ( MW in KD) , ( ng/mL ) = ( nM ) * ( MW in KD) , ( pg/mL ) = ( pM ) * ( MW in KD) .

### How will you prepare 1000 microgram ml stock solution of paracetamol?

Preparation of Standard Stock solution of PCM and PP: Accurately weighed quantity 100 mg of PCM and PP were transferred into separate 100 ml volumetric flask, dissolved and diluted up to mark with methanol(100 ml). This will give a stock solution having strength of 1000 μg/ml of each.

### What is microgram per ml?

A metric unit of mass concentration defined as the concentration of one gram of a substance per unit volume of the mixture equal to one cubic meter.

### Is microgram per ml a concentration?

Concentrations may be noted in equations as ug/mL, or micrograms per milliliter. One gram equals 1 million micrograms. Concentration also may be listed as parts per million. It is used to conveniently express very small concentrations of a compounds, such as contaminates in water.

### How many mg is in a mL of 1 solution?

So, a milligram is a thousandth of a thousandth of a kilogram, and a milliliter is a thousandth of a liter. Notice there is an extra thousandth on the weight unit. Therefore, there must be 1,000 milligrams in a milliliter, making the formula for mg to ml conversion: mL = mg / 1000 .

### How do you make a 5 mg mL solution?

All Answers (7) Somayeh, Dissolve 5 gram in 1000 ml : 5 mg /ml, Then 0.5 gram in 1000 ml : 0.5 mg /ml.

### How do you get 10 mg per mL?

1% = 1 g in 100 ml ( =1000mg in 100ml = 10mg in 1 ml)

### How do you make a 50 mg mL solution?

BCIP is sold as a disodium salt or as a p-toluidine salt. To prepare 50 mg/mL BCIP disodium salt, dissolve 0.5 g in 10 mL H2O.

### How do you dilute 4mg mL to 2mg mL?

Take 1 mL (4 mg) of the 4 mg/mL solution and mix with 1 mL of NS to obtain a final concentration of 2 mg/mL. Take 1 mL (5 mg) of the 5 mg/mL solution and mix with 9 mL of NS or D5W to obtain a final concentration of 0.5 mg/mL or 5 mg/10 mL.

### How to dilute 1 mg ml to 1ug ml?

For example, if a solution with a concentration of 1 mg/mL is diluted to yield a solution with a concentration of 1 μg/mL, the resulting dilution factor is 1000. For this particular dilution, it can also be said that the stock solution was diluted 1000-fold.

### How do you make a 0.1 M stock solution?

Take 1 part of your stock solution and add 9 parts of solvent (usually water but sometimes alcohol or other organic solvent). In all cases you are diluting by the same factor. The concentration of the resulting solution is 1M /10 = 0.1M where 10 is the dilution factor.

### How would you prepare 0.1 M solution from 1M solution?

If you dissolve 58.44g of NaCl in a final volume of 1 litre, you have made a 1M NaCl solution. To make a 0.1M NaCl solution, you could weigh 5.844g of NaCl and dissolve it in 1 litre of water; OR 0.5844g of NaCl in 100mL of water (see animation below); OR make a 1:10 dilution of a 1M sample.

### What is 1 mg equal to in micrograms?

A milligram (mg) of the object is equal to 1000 micrograms (μg).

### What does 1 microgram look like?

µg is the correct symbol for the metric measurement microgram which is one millionth of a gram or one thousandth of a milligram. The symbol for µ is a Greek letter (mu) which means ‘small’.

### Is micrograms per mL the same as PPM?

ug/mL↔ppm 1 ug/mL = 1 ppm.

### Is microgram a concentration?

Concentrations of chemicals in air are typically measured in units of the mass of chemical (milligrams, micrograms, nanograms, or picograms) per volume of air (cubic meter or cubic feet). However, concentrations may also be expressed as parts per million (ppm) or parts per billion (ppb) by using a conversion factor.

### Is 1 mg same as 1ml?

Is 1mg equivalent to 1ml? Conversion of a milliliter to milligram is very simple. Since 1 milligram is equal to 0.001 milliliters, which can be written as 1 mg = 1/1000 mL. Deriving from this equation, 1/1000 mL = 1 mg, hence 1 mL = 1000 mg.

### How much is 1mg to 1ml?

1 Milligram is equal to 0.001 milliliters.

### How do you make a 0.5 M solution?

If a different molarity is required, then multiply that number times the molar mass of NaCl. For example, if you wanted a 0.5 M solution, you would use 0.5 x 58.44 g/mol of NaCl in 1 L of solution or 29.22 g of NaCl.

### What does mg per ml mean?

Milligrams (mg) measure weight, and Millilitres (ml) measure volume of liquid. The part of the word ‘Milli’ comes from the latin mille, which means one thousand. There are 1,000 milligrams in a gram, and 1,000 millilitres in a litre of liquid.
