Question

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.

Answer 1

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

Step-by-step 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 =
`(1mol)/(342g)* 19g=0.055mol`

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