Concentrated hydrochloric acid has specific gravity of 1.18 and 36% hcl weight. What volume of concentrated hcl must be diluted to give 50 gm of 10 percent.
My calculation
50gm x 0.1 = 5gm
5gm x 36.5 = 182.5
182.5 / 0.36 = 506.9
506.9 / 1.18 = 430 ml This is answer. I am not sure answer. Please help
