Answer:
Mass = 199.21 g
Explanation:
Given data:
Moles of HCl = 3.59 mol
Mass of CaCl₂ = ?
Solution:
Chemical equation:
2HCl + Ca(OH)₂ → CaCl₂ + 2H₂O
we will compare the moles of HCl with CaCl₂ from balanced chemical equation:
HCl : CaCl₂
2 : 1
3.59 : 1/2×3.59 = 1.795
3.59 moles of HCl will produced 1.795 moles of CaCl₂.
Mass of CaCl₂.
Mass = number of moles × molar mass
Mass = 1.795 mol × 110.98 g/mol
Mass = 199.21 g
The element. in each square you can find the amount of subatomic particles, the mass, the atomic number, etc...
