Answer: Thus 8.41 g was the mass of the original sample
Explanation:
To calculate the moles :
According to stoichiometry :
As 3 moles of are produced by = 2 moles of
Thus 0.103 moles of are produced by =
of
Mass of
Thus 8.41 g was the mass of the original sample.
The answer is A.
During any chemical change the total mass doesn’t changes. Whatever the total mass of starting materials was present the same mass of ending products is present in a chemical reaction.
