Answer:
Sep by step to determine the mass of 25 mL of orange juice
Explanation:
Measure mass of container , then add 25 mL of OJ and subtract the difference
V = 15 L
PV = nRT
P = 1.29 atm, T= 355 K mass argon 40g/mol
n = mass/ molecular mass; n = 26.6 g/40 g/mol; n = 0.665 mol
V = (0,665 mol x 0.082 x 355 K) / 1.29 atm = 15 L
