Wich has a larger percent by mass of sulfur - H2SO or H2S7O8?
Pie

Answer:

Explanation:

H2SO4 let S be x

2(1) + x + 4(-2) = 0

2 + x - 8 = 0

x - 6 = 0

x = 6

For H2S7O8 let S be x

2(1) + 7(x) + 8(-2) = 0

2 + 7x - 16 = 0

7x - 14 = 0

7x = 14

x = 14/7

x = 2

:- H2SO4 as the larger percentage
