A sample of oxygen gas has volume 150.0 mL, at 0.947 atm, what will be the volume of the gas at 750.12 mm of Hg if temperature remain constant.

143.9 mL

Explanation:

Applying,

PV = P'V' Equation 1

Where P = Initial pressure, V = Initial Volume, P' = Final pressure, V' = Final volume.

Make V' The subject of equation 1

V' = PV/P' Equation 2

From the question,

Given: P = 0.947 atm, V = 150 mL, P' = 750.12 mm of Hg = (750.12/760) = 0.987 atm,

Substitute these values  into equation 2

V' = (0.947×150)/0.987

V' = 143.9 mL

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
