Question

Two moles of copper (II) sulfate,CuSO4,contains blank moles of O

Answer 1

8 mol

Step-by-step explanation:

Step 1: Given data

Moles of copper (II) sulfate: 2 mol

Chemical formula of copper (II) sulfate: CuSO₄

Step 2: Establish the molar ratio of copper (II) sulfate to oxygen

According to the chemical formula, the molar ratio of copper (II) sulfate to oxygen is 1:4.

Step 3: Calculate the moles of O in 2 mol of CuSO₄

`2molCuSO_4 * (4molO)/(1molCuSO_4) = 8molO`
