Well approx. $\frac{4}{5} \cdot a t m$ $4/5*atm$ .........

Explanation:

So partial pressures of the constituent gases are.......

$P_{N_{2}} = 0.78 \times 1 \cdot a t m$ $P_(N_2)=0.78xx1*atm$ ; $P_{O_{2}} = 0.21 \times 1 \cdot a t m$ $P_(O_2)=0.21xx1*atm$ ; and $P_{other gases} = 0.01 \times 1 \cdot a t m$ $P_("other gases")=0.01xx1*atm$ .

Does the sum of the partial pressures add up to $P_{atmospheric}$ $P_"atmospheric"$ ? Why should it?
