Question

Mass of 0.2 mole of magnesium oxide

Answer 1

Answer:

8g

Explanation:

number of moles=given mass\molar mass

$.2 = x \div 40$

x=8g

Answer 2

Explanation:

molecular mass of magnesium oxide=24+16

40

if 1 mole=40, then 0.2 mole=?

let's consider the atomic mass as 'x'

x=0.2×40

x=8g.
