Question #c446e

Answer 1

Use Dalton's law. Answer is:

`p_(Xe)=462.71` `mmHg`

Explanation:

Dalton's law states that:

`p_i/(Σp_i)=n_i/(Σn_i)`

where `p_i` is the pressure and `n_i` are the moles of each individual gas and `Σ` is the notation of their sum `(Σx_i=x_1+x_2+...)`.

`Σp_i=1560` `mmHg`

`Σn_i=1.5+2.65+1.75=5.9` `mol`

By using Dalton's law on `Xe`:

`p_(Xe)/(Σp_i)=n_(Xe)/(Σn_i)`

`p_(Xe)=n_(Xe)/(Σn_i)*Σp_i=1.75/5.9*1560` `cancel(mol)/cancel(mol)*mmHg`

`p_(Xe)=462.71` `mmHg`
