A gas at pressure 912 mm of hg has volume 450 cm cube.what will be volume at 0.4 ATM
convert atm to mm⋅hg
volume is inversely proportional to pressure
(912 mm⋅hg) / (0.4 atm) = ? / 450 cm^3
My answer is same

100 present correct
The answer is 1350
According to boyles law
P1=912mmhg
V1=450cm3
P2=0.4 ×760mm=304
V2=?
V2=p1v1÷p2
To calculate the volume of a gas at a different pressure, you can use Boyle's law, which states that the pressure and volume of a gas are inversely proportional, as long as the temperature remains constant. Boyle's law can be expressed as:
P1 * V1 = P2 * V2
Where:
P1 = Initial pressure (912 mmHg)
V1 = Initial volume (450 cm^3)
P2 = Final pressure (0.4 atm)
V2 = Final volume (which we need to calculate)
Rearranging the formula, we have:
V2 = (P1 * V1) / P2
Now we can substitute in the values:
V2 = (912 mmHg * 450 cm^3) / 0.4 atm
However, we need to ensure that the units are consistent. Since 1 atm is equal to 760 mmHg, we can convert the pressure to atm:
V2 = (912 mmHg * 450 cm^3) / (0.4 atm * (760 mmHg / 1 atm))
Simplifying further:
V2 = (912 * 450) / (0.4 * 760) cm^3
V2 ≈ 511.87 cm^3
Therefore, the volume of the gas at 0.4 atm would be approximately 511.87 cm^3.
