I just need answers for this 4 question please help

A typical barometric pressure in Denver, Colorado, is $615.5\mathrm{mm}\mathrm{Hg}$. What is this pressure in bar? A medical laboratory catalog describes the pressure in a cylinder of a gas as $14.95\mathrm{MPa}$. What is this pressure in psi? (1 psi = 6894.8 $\mathrm{Pa})$ The pressure of a sample of gas is measured at sea level with a open-end manometer. The liquid in the manometer is mercury. Assuming atmospheric pressure is $760.0\mathrm{mm}\mathrm{Hg}$, determine the pressure of the gas in torr. The pressure of a sample of gas is measured at sea level with a open-end manometer.
