Help me plsss What is the mass in grams of H₂ that can be formed from 47.2 grams of NH₃ in the following reaction?
2 NH₃(g) → 3 H₂(g) + N₂(g)

8.34

Explanation:

1) how much moles of NH₃ are in the reaction;

2) how much moles of H₂ are in the reaction;

3)  the required mass of the H₂.

all the details are in the attachment; the answer is marked with red colour.

Note1: M(NH₃) - molar mass of the NH₃, constant; M(H₂) - the molar mass of the H₂, constant; ν(NH₃) - quantity of NH₃; ν(H₂) - quantity of H₂.

Note2: the suggested solution is not the shortest one.

your parents i think this could be it

explanation:

0.07 g/cm³

1.37 g/cm³
