Nitrogen is often used for the storage of semen samples for artificial insemination of cattle. Nitrogen is used to maintain a dry inert atmosphere over chemicals during storage, reaction or processing. Used in brewing, soft drinks and wine-making industries to exclude air from the product and de-aerate water.
<u>Answer:</u> The molar mass of the unknown protein is 6387.9 g/mol
<u>Explanation:</u>
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
or,
where,
= osmotic pressure of the solution = 0.0766 atm
i = Van't hoff factor = 1 (for non-electrolytes)
Mass of protein = 100. mg = 0.100 g (Conversion factor: 1 g = 1000 mg)
Molar mass of protein = ?
Volume of solution = 5.00 mL
R = Gas constant =
T = temperature of the solution =
Putting values in above equation, we get:
Hence, the molar mass of the unknown protein is 6387.9 g/mol
