Answer:
0.001 kilograms by divde the mass value by 1000
Answer:
225.4 g
Explanation:
The equation of the reaction is;
Zn(s) + FeNiO(s) ------> ZnFeNiO(s)
Since FeNiO is in excess then Zn must be the limiting reactant.
Molar mass of Zn = 65.38gmol-1
Number of moles of Zn reacted = 75g/65.38gmol-1 =1.15 moles
If 1 mole of Zn yields 1 mole of ZnFeNiO
1.15 moles of Zn yields 1.15 moles of ZnFeNiO
Mass of ZnFeNiO produced= 196gmol-1 * 1.15moles = 225.4 g
