Hope it helps :)
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.
