Explanation:
21.0 g of potassium reacts with 62.5 g of barium nitride, what mass of potassium nitride will be produced
Answer is: metal is lead with density of 11,4 g/cm³.
Text that missing: a sample of an unkwown metal has a mass of 35,4 g and a volume of 3,11 cm³.
m(metal) = 35,4 g.
V(metal) = 3,11 cm³.
d(metal) = m(metal) ÷ V(metal)
d(metal) = 35,4÷ g ÷ 3,11 cm³
d(metal) = 11,4 g/cm³.
