Answer 2

Answer:

The answer is c)2 moles of NH3

Explanation:

1 mole of CH4 = 16g

0.5 moles of CH4 = 8g

= 3.011 x 10^23 molecules

1 molecule of CH4 = 5 atoms

3.011 x 10^23 molecules =  5 x 3.011 x 10^23 = 1.5 x 10^24 atoms

22.4 l of CO2 = 1 mole

5.6 moles of CO2 = 0.25 moles = 1.5 x 10^23 molecules

1 molecule of CO2 = 3 atoms

1.5 x 10^23 molecules = 4.5 x 10^23 atoms

2 moles of NH3 = 1.20 x 10^24 molecules

1 molecule of NH3 = 4 atoms

1.20 x 10^24 molecules = 4.8 x 10^24 atoms

4 g of He gas = 1 mole

8 g of He gas = 2 moles

2 moles of He = 1.2 x 10^24 atoms
