lorasvet [3.4K]
The answer is (2) 0.2. The unit of M means 1 mol/L. The conversion of liter and milliliter is 1 liter equals 1000 milliliters. So the molar number of solute is 1*0.2=0.2 mol.

What is the mass of solute in a 500 mL solution of 0.200 M
Fofino [41]

16.4 grams is the mass of solute in a 500 mL solution of 0.200 M .

sodium phosphate

Explanation:

Given data about sodium phosphate

atomic mass of Na3PO4 = 164 grams/mole

volume of the solution = 500 ml or 0.5 litres

molarity of sodium phosphate solution = 0.200 M

The formula for molarity will be used here to know the mass dissolved in the given volume of the solution:

The formula is

molarity = \frac{number of moles of solute}{volume in litres}

    putting the values in the equation, we get

molarity x volume = number of moles

0.200 X 0.5= number of  moles

number of moles = 0.1 moles

Atomic mass x number of moles = mass

putting the values in the above equation

164 x 0.1 = 16.4 grams

16.4 grams of sodium phosphate is present in 0.5 L of the solution to make a 0.2 M solution.

Example:-

(i) HCl + NaOH ---> NaCl + HOH

(ii) H2SO4 + 2NH4OH ---> (NH4)2SO4 + 2HOH.
