Question

A teaspoon of table sugar contains about 0.01 mol sucrose. What is the molarity of sucrose if a teaspoon of sugar has been dissolved in a cup of tea with a volume of 300 mL ?

.033 M

.003 M

30 M

.0003 M

Answer 1

The answer to your question is 0.033 M

Step-by-step explanation:

Data

moles of sucrose = 0.01

Molarity = ?

Volume = 300 ml

Formula

`Molarity = (moles)/(volume)`

Process

1.- Convert volume to liters using proportions

1000 ml --------------------- 1 liter

300 ml ------------------- x

x = (300 x 1) / 1000

x = 300 / 1000

x = 0.3 liters

2.- Substitute values in the formula

`Molarity = (0.01)/(0.3)`

3.- Simplification and result

Molarity = 0.033
