1.
(P1V1/T1) = (P2V2/T2)
2.
mols = grams/molar mass
(P1V1/T1) = (P2V2/T2)
2.
mols = grams/molar mass

Answer: 1.20 x 10^3
Explanation: 822/325 = ?/475
Isolate the unknown by multiplying both sides by 475/1 (reciprocal). So you divided 822 by 325 and get 2.529230769. You take that and multiply it by 475 and get 1201, which equals1.20 x 10^3.
