Answer:
Step-by-step explanation:
Let Harry = x
Tom = harry + 2
Tom = x + 2
Ben + 3 = harry
harry - 3 = ben
x - 3 = ben
Tom + harry + Ben = 65
x + 2 + x + x - 3 = 65
3x - 1 = 65 Add 1 to both sides
3x = 65 + 1
3x = 66 Divide by 3
x = 66/3
x = 22
So harry = 22 kg

</span><span>the number of moles of sulfate in the sample
M = m /n
M molar mass
m mass
n number of moles
so n =m/M
n = 8.642/233.33=0.037mol
