Question

0.3 moles of methane find weight

Answer 1

Explanation:

molar mass of ch4 =12+4=16

number of moles =mass/molar mass

0.3=mass/16

mass= 4.8

so. weight =4.8

Answer 2

Methane = CH4
Mass = 12+4(1) = 16

1 mole mass = 16
0.3 mole mass = X

Thus X = 16(0.3) / 1
= 4.8 g
Mass of 0.3mole of methane is 4.8g
