Answer: NH3 = 9/5 H20= 9/2
Explanation:
Mr of NH3 = 17g/mol
Mr of H20 = 18g/mol
NH3 = 30.6g divide by 17g/mol = 1.8 mol
= 9/5
H20 = 81.3g divide by 18g/mol = 4.5 mol
= 9/2
Answer:
0.286 moles

False
Few organisms were not preserved as well as others, and new fossils are found every day
1) 4
2) 1/9
3) 46.5
4) 5.8
Density= Mass/Volume
1) D=24/6=4
2) D=1/9=0.11
3) D=2000/43=46.5
4) D=75/13=5.8
