Ateaspoon 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

The answer to your question is 0.033 M

Explanation:

Data

moles of sucrose = 0.01

Molarity = ?

Volume = 300 ml

Formula

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

3.- Simplification and result

                      Molarity = 0.033

yes the answer is total mass in unchanged   : )
