The mass of 50% is 200 g
Explanation:
The given equation is
From this it is clear that 1 mole of will produce 1 mole of
Given that mass of produced = 136 g
Molar weight of = 136
Thus, moles of produced = Mass/Molar mass = 136/136 = 1 mole
Thus, moles of utilised = 1
We know that in 1 mole there are 100 gram of
Thus, mass of = 100
But it is given that is only 50% pure
Thus, total mass of = 200 g
Hope this answer is helpful.
