Answer: 43.2 grams
Explanation:
Given that,
Amount of moles of NH4 (n) = 2.4
Mass of NH4 in grams (m) = ?
For molar mass of NH4, use the molar masses of:
Nitrogen, N = 14g;
Hydrogen, H = 1g
NH4 = 14g + (1g x 4)
= 14g + 4g
= 18g/mol
Since, amount of moles = mass in grams / molar mass
2.4 mole = m / 18g/mol
m = 2.4 mole x 18g/mol
m = 43.2g
Thus, there are 43.2 grams in 2.4 moles of NH4.
