Answer : The maximum number of grams of formed is, 8.955 g
Solution : Given,
Mass of phosphorous = 8.2 g
Mass of hydrogen = 4 g
Molar mass of = 123.6 g/mole
Molar mass of = 2.016 g/mole
Molar mass of = 33.924 g/mole
The balanced chemical reaction is,
First we have to calculate the moles and
From the reaction, we conclude that
1 mole of react with 6 moles of
0.066 moles of react with
moles of
That means the is in excess amount and
is in limited amount.
Now we have to calculate the moles of .
As, 1 mole of react to give 4 moles of
So, 0.066 moles of react to give
moles of
Now we have to calculate the mass of
Therefore, the maximum number of grams of formed is, 8.955 g
