Acceleration = = 15m/s²
Answer:
The required new pressure is 775 mm hg.
Explanation:
We are given that gas has a volume of 185 ml and a pressure of 310 mm hg. The desired volume is 74.0 ml.
We have to find the required new pressure.
Let the required new pressure be ''.
As we know that Boyle's law formula states that;
where, = original pressure of gas in the container = 310 mm hg
= required new pressure
= volume of gas in the container = 185 ml
= desired new volume of the gas = 74 ml
So,
= 775 mm hg
Hence, the required new pressure is 775 mm hg.
