To find the mass of (5.30 \times 10^{22}) formula units of Ba(NO₃)₂, you multiply the number of formula units by the molar mass of Ba(NO₃)₂.
(5.30 \times 10^{22}) formula units × molar mass of Ba(NO₃)₂ = mass
(5.30 \times 10^{22}) formula units × 261.35 g/mol = mass
Mass = (1.385 \times 10^{25}) grams
