If the pressure is reported as 750*mm*Hg750mmHg, what is the pressure in atmospheres?

1 Answer

11 atmatm -= 760760 mmmm HgHg

Explanation:

It makes sense to preconvert the pressure measurement ot atmospheres. So P_1P1 == (750*mm*Hg)/(760mm*Hg*atm^-1)750mmHg760mmHgatm1 == ???? atmatm

Since amount of gas is constant, use the combined gas law (P_1V_1)/T_1P1V1T1 == (P_2V_2)/T_2P2V2T2, and solve for V_2V2.

You are only justified in quoting an answer to 1 decimal place, as this was the accuracy of the initial conditions.
