Answer:
1.126 x 10^22
Explanation:
pV = nRT
7.53 x 10 = n x 8.31 x 485
n = (7.53 x 10) / (8.31 x 485) = 0.0187 moles
M = n x Avogadros number
0.0187 x 6.02 x 10^23 = 1.126 x 10^22
the answer is D. just took the test
Answer:
0.64 g O₂
Explanation:
I am assuming you meant 0.02 moles of O₂. In that case, convert moles to mass via stoichiometry:
0.02 mol O₂ x 32 g O₂/1 mol O₂ = 0.64 g O₂
