What mass of salt can be obtained by reacting 20 g of magnesium oxide with a nitric acid solution?

univerkov | December 3, 2020 | education

MgO + 2HNO3 = Mg (NO3) 2 + H2O
n (MgO) = m \ M = 20 \ 40 = 0.5 mol
n (Mg (NO3) 2) according to the reaction equation = 0.5 mol
m (Mg (NO3) 2) = nM = 0.5 * 148 = 74 g
Answer: 74 g
