Question

What is the %w/w of a 500 mL solution of HCl that has a density of 1.169 g/mL and was made using 386 g of water?

I'm having a lot of trouble with this Q. Thanks to anyone who helps

Answer 1

500 mL with a density of 1.169 g/mL
... has a total mass of ... 500 * 1.169 = 585 g

the mass of the water is 386 g

the %w/w is ... [(585 - 386) / 585] * 100%
