Answer:
V₂ = 236.84 mL
Explanation:
The relation between pressure and volume is inverse.
We can write it as follows :

We have,
P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.
So,

So, the new volume of the gas is 236.84 mL.
I believe the statement that is true of metals and metalloids is B. Metals are good conductors and metalloids are bad conductors.
