Question

What is the mass of 0.2 mole of oxygen atoms?

Answer 1

Here is your answer.......

Mass of oxygen=16g

mole=given mass/ atomic mass

0.2 mole of oxygen is (GIVEN),

Then,
0.2 =given mass/ 16

given mass=0.2 ×16
➡3.1 g

Answer 2

Dear Student,

◆ Answer -

Mass of oxygen = 3.2 g

● Explaination -

# Given -

Moles of oxygen = 0.2 mol

# Solution -

As we know, molar mass of oxygen is 16 g/mol.

Mass of oxygen will be calculated by formula -

Mass of oxygen = no of moles × molar mass

Mass of oxygen = 16 × 0.2

Mass of oxygen = 3.2 g

Therefore, mass of oxygen is 3.2 g.

Thanks dear. Hope this helps you...
