Question

What is the mass of 3.45 moles of NH4NO3?

Answer 1

276 u is mass of NH4NO3 of 3.45 mole of it

Answer 2

Mass of one mole of NH4NO3 = 80.052 g

( mass of 1mole of nitrogen = 14.00672g

oxygen = 15.99943g. hydrogen= 1.007947g)

then, mass of 3.45 mole of NH4NO3 = 3.45 x 80.052 = 276.179g
