Question

Find total mass
1) 2 moles of Nitrogen gas
2) 2 moles of Nitrogen atoms
3) 0.5 moles of water
4) 5 moles of H2S04
5) 3 moles of Ammonia​

Answer 1

Explanation:

1) 1 mole weighs = 28 grams

2 mole weighs = 2 × 28

= 56 grams

2) 2× 14 = 28 grams

Answer 2

Answer:

1) nitrogen gas = N2

mass= 14×2

=28

2 mole = 2× 28

= 56g

2) Nitrogen= N

14

2 mole = 14×2

28 g

3) water = H20

mass 18u

18×o.5

9 g

4) The molar mass of hydrogen is 1

Molar mass of sulphur (S) is 32

Molar mass of oxygen (O) is 16

2(1)+32+4(16) = 98

Molar mass of sulphuric acid H2SO4 is 98

5 X 98 =490

5) 3 mole of amonia = 18 u

3mole = 3× 18

= 54
