Answer : The mass of added must be, 61.9 grams
Explanation : Given,
Mass of = 40 g
Molar mass of = 105.9 g/mol
First we have to calculate the moles of .
Now we have to calculate the moles of
The balance chemical reaction will be:
From the balanced reaction we conclude that
As, 1 mole of react with 1 mole of
So, 0.378 mole of react with 0.378 mole of
Now we have to calculate the mass of
Molar mass of = 164 g/mol
Thus, the mass of added must be, 61.9 grams
