Answer:
Explanation:
A. 64 g O2(1 mole/32 g)(6.023x10^23molecules/mole)=12.04x10^23 =1.204x10^24
B. hydrogen 10 g/2 g/mol =(5 mol) 6.023 x 10^23
helium 10g/4g/mol=(2.5 mol)(6.023x10^23
C. 0.5molO2 x32 g/mol= 16g
D. (3.011 x10^23 atoms/6.023 x 10^23 atoms/mol)x (12g/mol)=6g
E. (58.5g/mol) x 10 mol= 585 g
