Question

How do you convert the following? A)0.56 mol C6H6 to molecules C6H6 B) 4.25x10^-4 mol to H2SO4 to grams

Answer 1

a. `3.3712*10^(23)`

b. `0.04165g`

Explanation:

a. `a=nL`, where:
- `n` = number of moles (`mol`)
- `L` = Avogradro's constant (`~~6.02*10^(23)` `mol^(-1)`)
- `a` = number of molcules/ions/atoms

`a=(6.02*10^(23))(0.56)=3.3712*10^(23)`

b. `m/M=n`, where:

• `m` = mass (`g`)
• `M` = molar mas (`g` `mol^(-1)`)
• `n` = number of moles (`mol`)

`m=Mn=(4.25*10^(-4))(2(1)+32+4(16))=0.04165g`
