Answer: 2.8 moles of copper (Il) sulfide will be produced from 2.8 moles of sulphur.
Explanation:
The balanced chemical reaction is:
According to stoichiometry :
1 mole of produce = 1 mole of copper (Il) sulfide
Thus 2.8 moles of will produce= of copper (Il) sulfide
Thus 2.8 moles of copper (Il) sulfide will be produced from 2.8 moles of sulphur.
Answer:
The percentage of N in the compound is 0.5088
Explanation:
Mass of compound = 8.75 mg = 8.75×1000 = 8750 g
Mass of N2 = number of moles of N2 × MW of N2 = 1.59 × 28 = 44.52 g
% of N in the compound = (mass of N2/mass of compound) × 100 = (44.52/8750) × 100 = 5.088×10^-3 × 100 = 0.5088
