Answer:
10.418*10²³
Explanation:
1) 6.022*10²³ moleculas in 1 mole PCl₅ (Avogadro's number);
2) in 1.73 moles: 6.022*10²³*1.73=10.418*10²³
Answer:
1040 g HCl
Explanation:
Al(OH)₃ + 3HCl => AlCl₃ + 3H₂O
moles Al(OH)₃ = 750g/78g·mol⁻¹ = 9.62 mol
moles HCl used = 3 x moles Al(OH)₃ consumed = 3(9.62)mol HCl = 1038.46 g. ≈ 1040 g HCl (3 sig.figs.)
