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

1 Answer

1 atm -= 760 mm Hg

Explanation:

It makes sense to preconvert the pressure measurement ot atmospheres. So P_1 = (750*mm*Hg)/(760mm*Hg*atm^-1) = ?? atm

Since amount of gas is constant, use the combined gas law (P_1V_1)/T_1 = (P_2V_2)/T_2, and solve for V_2.

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