Answer:
The mass of zinc sulfide produced is
Explanation:
From the question we are told that
The mass of zinc is
The mass of sulfur is
The molar mass of is a constant with value 65.39 g /mol
The molar mass of is a constant with value 32.01 g/mol
The molar mass of is a constant with value 97.46 g/mol
The reaction is
So from the reaction
1 mole of react with 1 mole of
to produce 1 mole of
This implies that
65.39 g /mol of react with 32.01 g/mol of
to produce 97.46 g/mol of
From the values given we can deduce that the limiting reactant is sulfur cause of the smaller mass
So
0.250 g of react with 0.250 of
to produce
of
So
Thus the mass of the mass of zinc sulfide produced is
