Question

What is the mass of 1.00 mol of oxygen (O2)?

Answer 1

Mass = 32 g

Step-by-step explanation:

Given data:

Number of moles of oxygen = 1.0 mol

Mass of oxygen = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of oxygen (O₂) is 32 g/mol

by putting values,

1.0 mol = mass/ 32 g/mol

Mass = 1.0 mol ×32 g/mol

Mass = 32 g
