What is the mass of 4 moles of hydrogen gas in expanlantion
​

Answer 1

Answer:

4g

Explanation:

the answer to this question is 4g because of the formula

no of moles  =    given mass/molar mass

4=x/1

x=4g

Answer 2

To calculate: Mass

Given : 4 moles of Hydrogen gas (H)

Atomic Mass of H = 1

1 mole of H = GAM (Gram Atomic Mass) of H

1 mole of H = 1g

Therefore in 4 moles,

4 moles = 1 × 4

= 4g

Hence, in 4 moles of Hydrogen gas, 4g of mass will be there.
