The mass of one mole of sugar is 342 g. you used 19 g of sugar. calculate the number of moles of sugar you used.

The number of moles of sugar that is used are 0.055 moles.

Explanation:

We are given:

Mass of 1 mole of sugar = 342 g

Mass of sugar used = 19 g

So, by applying unitary method, we get:

342 grams of sugar is making 1 mole

So, 19 grams of sugar will make =

Hence, the number of moles of sugar that is used are 0.055 moles.
