Question

6 What is the concentration of sugar (C12H22011
in mol L- if its 20g are dissolved in
enough water to make a final volume
up to 2l?​

Answer 1

Answer:

0.029M or 2.9%

Explanation:

molar mass of sugar=342g/mol

mass of sugar=20g

moles of sugar=20/342=0.058mol

volume of solution =2L

concentration in mol/L is its molarity

molarity=moles/volume in L=0.058/2=0.029M
