Question

How many grams of sucrose(342g/mole) are needed to make 1L of 1M solution?

Answer 1

A 1M solution would consist of 342.3 grams sucrose in one liter final volume. A concentration of 70 mM is the same as 0.07 moles per liter. Take 0.07 moles/liter times 342.3 grams per mole and you have 23.96 grams needed per liter. To make 200 milliliters of your solution multiply grams/liter by liters needed.

Answer 2

342.3 grams

The formula weight for sucrose is identical to its molecular weight, namely 342.3 grams per mole. A 1M solution would consist of 342.3 grams sucrose in one liter final volume.
