Copper (II) chloride has a molar mass of 134.452 g/mol. What is the mass of 2.17 moles?

Answer 1

Answer:

292 g

Explanation:

Step 1: Given data

• Molar mass of copper (II) chloride (M): 134.452 g/mol

• Moles of copper (II) chloride (n): 2.17 mol

• Mass of copper (II) chloride (m): ?

Step 2: Calculate the mass corresponding to 2.17 moles of copper (II) chloride

We will use the following expression.

m = n × M

m = 2.17 mol × 134.452 g/mol = 292 g

2.17 moles of copper (II) chloride weigh 292 g.
