Question

Which has more mass?

a
1 mole of Carbon
b
1 mole of Oxygen
c
1 mole of Chlorine
d
1 mole of Hydrogen

Answer 1

Chlorine has more mass than the other elements.

Step-by-step explanation:

We can find the mass of each element using the following equation:

`m = \eta*A`

Where:

η: is the moles

A: is the standard atomic weight

a) For carbon, we have:

`m_(C) = \eta*A = 1 mol*12.011 g/mol = 12.011 g`

b) For oxygen, we have:

`m_(O) = 1 mol*15.999 g/mol = 15.999 g`

c) For chlorine, we have:

`m_(Cl) = 1 mol*35.45 g/mol = 35.45 g`

d) And for For hydrogen, we have:

`m_(H) = 1 mol*1.008 g/mol = 1.008 g`

Therefore, chlorine has more mass than the other elements.
