Answer 1

9.03 × 1016 -> 1.5 × 10-7 moles of helium

2.709 × 1024 -> 4.5 moles of nitrogen

1.9264 × 1028 -> 3.2 × 104 moles of hydrogen

4.8762 × 1014 -> 8.1 × 10-10 moles of xenon

hope this helps

Answer 2

9.03x10^16---------1.5x10^-7 helium

2.709x10^24-------4.5 nitrogen

1.9264x10^28-------3.2x10^4 hydrogen

4.8782x10^14--------8.1x10^-10 xenon

Step-by-step explanation: i got it right PERIOD PURRRRR
