Answer: 0.25 g
I just took this test and that was the answer to it.
To solve this, we need the Avogadros number to convert to
moles then multiply with molar mass to convert to mass in grams.
moles = 9.3 x 10^23 molecules * (1 mol / 6.022 x 10^23
molecules)
moles = 1.54 moles
Molar mass of NH3 is 17 g/mol:
mass = 1.54 moles * 17 g/mol
<span>mass = 26.25 g</span>
