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
