How many ml of HCl required to prepare 5% of HCl solution in 750ml water.if HCl is 36% pure and specific gravity is 1.18g/ml?

Answer 1

What is the molarity (M) of the HCl? That's
1000 mL x 1.18 g/mL x 0.36 x (1/36.5) = ?
Then use mL1 x M1 = mL2 x M2. Substitute and solve for the unknown. Post your work if you get stuck.
