Question

How many moles of hydrogen are needed to produce 34.5 grams of ammonia

Answer 1

According to the formula of mass in grams

Mass in grams= Moles/ Molar mass

Rearranging the formula

Moles= Mass/ Molar mass

Given:

Mass: 34.5 g

Molar mass: NH3

: 14 + 1×3

: 17g

Moles: ?

Solution:

Moles= Mass/ Molar mass

= 34.5 / 17

Moles= 2.025 mol

Answer:

So 2.025 moles of hydrogen are needed produce 34.5 grams of ammonia
