Question

jones soda contains 33g added sugar in a 355 ml bottle. calculate the molarity of sugar in this beverage
0.56M
15.4M
0.51M
0.00051M

Answer 1

The molarity of sugar in this beverage : 0.51 M

Explanation:

Given

mass of soda=solute=33 g

volume of bottle=solution=355 ml

Required

the molarity of sugar

Analysis

• Convert mass to mol of sugar

• Find molarity :

$\tt M=\dfrac{n}{V}$

Solution

• mol of sugar-C₆H₁₂O₆(MW=180.16 g/mol g/mol)

$\tt mol=\dfrac{33}{180.16 g/mol g/mol}=0.1832$

• molarity(volume=355 ml=0.355 L)

$\tt M=\dfrac{0.1832}{0.355}=0.51~M$
