Asolution is prepared by dissolving 4.78 g of an unknown nonelectrolyte in enough water to make 375 ml of solution. the osmotic pressure of the solution is 1.33 atm at 27c. what is the molar mass of the solute?

The molar mass of the solute is 236.0 g/mol

Explanation:

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

where,

= osmotic pressure of the solution = 1.33 atm

i = Van't hoff factor = 1 (for non-electrolytes)

M = molarity of solute = ?

R = Gas constant =

T = temperature of the solution =

Putting values in above equation, we get:

To calculate the molecular mass of solute, we use the equation used to calculate the molarity of solution:

We are given:

Molarity of solution = 0.0540 M

Given mass of solute = 4.78 g

Volume of solution = 375 mL

Putting values in above equation, we get:

Hence, the molar mass of the solute is 236.0 g/mol

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
