A50 ml sample of calcium hydroxide solution required 19.50 ml of 0.1050n hcl titration. calculate the amount of calcium hydroxide in the 50 sample?

The reaction of calcium hydroxide (Ca(OH)2) and hydrochloric acid (HCl) is:
Ca(OH)2 + 2HCl --> CaCl2 + 2H2O. So the amount of calcium hydroxide in the sample is ((19.50ml HCl)/1000) x 0.1050 mol/L 
From the balanced equation above: (1 mol Ca(OH)2 / 2 mol HCl) 
Calculating the amount of Ca(OH)2 in the 50ml sample, multiply with the molar mass: 
((19.50ml HCl)/1000) x 0.1050 mol/L x (1 mol Ca(OH)2 / 2 mol HCl) x 74.039 g/mol

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer
