Question

What would be the mass, in grams, of 1.505 x 10^23 molecules of carbon disulfide (CS2)?

Answer 1

To Find :

The mass, in grams, of
`1.505 * 10^(23)` molecules of carbon disulfide (CS₂).

Solution :

Molecular mass of CS₂ = 76 gm/mol .

It means that mass of
`6.022 * 10^(23)` molecules of CS₂ is 76 gm/mol.

Let, mass of
`1.505 * 10^(23)` molecules of carbon disulfide (CS₂) is x.

So,

`x= 76* (1.505 * 10^(23))/(6.022* 10^(23))\\\\x = 76 * (1.505)/(6.022)\\\\x = 19 \ gm`

Therefore, the mass in gram is 19 gm.
