Answer:
90g of Ca(OH)2
Explanation:
2HCl + Ca(OH)2 —> CaCl2 + 2H20
Molar Mass of Ca(OH)2 = 40 + 2( 16 + 1) = 40 + 2(17) = 40 + 34 = 74g/mol
Molar Mass of CaCl2 = 40 + (2 x 3.5) = 40 + 71 = 111g/mol
From the equation,
74g of Ca(OH)2 produced 111g of CaCl2.
Therefore, Xg of Ca(OH)2 will produce 135g of CaCl2 i.e
Xg of Ca(OH)2 = (74 x 135) / 111 = 90g.
Therefore, 90g of Ca(OH)2 are required to produce 135g of CaCl2
