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
NaCl is made of Na and Cl
The molar mass of Na = 22.989 g/mol
The molar mass of Cl = 35.453 g/mol
Molar mass of NaCl = 22.989 + 35.453
= 58.44 g/mol
