Which among the following is the heavist?

Options

A. 1 mol of oxygen
B. One molecule of sulphur trioxide
C. 100 amu of uranium
D. 100 mol of hydrogen

Explanation

Finding the masses of others
`1 mol O_(2) = 32g`
1 molecule `SO_(2) = (64g mol^(-1))/(6.022xx10^(23) "molecules" mol^(-1))`
`= 10.62xx10^(-23)g`
`= 1.062xx10^(-22)g`
100 amu of uranium `= 100 am u xx (1.66xx10^(-24)g)/(1 am u)`
`= 1.66xx10^(-24)g`
`10 mol` of hydrogen `= (10 mol) (2g mol^(-1)) = 20g`
