Muriatic acid is the commercial name for hydrochloric acid that can be purchased from hardware stores as a solution that is 28% (w/w) hcl. what mass of this solution contains 15 g of hcl?

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

idk what the question is about

the correct answer would be b) volume versus temperature, because they are also directly proportional.
