Question

How many moles of Csl are in 82.0 grams of Csl?

Answer 1

.315mol CsI

Explanation:

CsI has a molar mass of 260 g/mol. This means that one mole of cesium iodide has a mass of 260 grams. We can use stoichiometry/dimensional analysis to figure out how many moles is equal to 82 grams.

`82.0g CsI ((1 mole)/(260g) ) = .315mol CsI`
