Answer : The mass of is, 9.64 grams.
Explanation : Given,
Mass of = 54.6 g
Molar mass of = 17 g/mol
Molar mass of = 2 g/mol
First we have to calculate the moles of .
Now we have to calculate the moles of
The balanced chemical equation is:
From the balanced reaction we conclude that
As, 2 mole of react to give 3 moles of
So, 3.21 mole of react to give mole of
Now we have to calculate the mass of
Therefore, the mass of is, 9.64 grams.

(5.3 x 10⁴) + (1.3 x 10⁴) =6.6 x 10⁴
(7.2 x 10⁻⁴) ÷ (1.8 x 10³)=4 x 10⁻⁷
10⁴ x 10⁻³ x 10⁶=10⁷
(9.12 x 10⁻¹) - (4.7 x 10⁻²)=(9.12 x 10⁻²) - (4.7 x 10⁻²)
=(91.2-4.7) x 10⁻²
=85.5 x 10⁻²
