A 17% by mass H2SO4 (aq) solution has a density of 1.07 g/cm^3. what is the molality of H2SO4 in solution?

there all right good

explanation:

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

answer; 4 electrons;
