Concentrated hydrochloric acid is an aqueous solution that is 37.2 % hcl by mass. the density of the solution is 1.19 g/ml. what mass of hcl is contained in 0.853 l of solution?

Ω (HCl) =37,2% = 0,372 - mass percent.
d (HCl) = 1,19 g/cm³, 1ml = 1cm³ - density.
V (HCl) = 0,853l = 0,853 dm³ = 0,853·1000 = 853 cm³ - volume.
mr (mass of solution) = d·V = 1,19 g/cm³ · 853 cm³ = 1015,07 g.
mrs (HCl -mass of solute) = ω·mr = 0,372·1015,07g = 377,6g = 0,3776 kg.
