, it occupied 1500 cm". What was the initial pressure if the temperature was kept
constant during the complete operation?
Solution :​

Answer 1

Answer:

5 atm , please make Brainliest

Explanation:

According to Boyle's Law,

P1V1 = P2V2

P1 = ?

P2= 2.5

V1=750

V2=1500

so,

P1 = P2V2/V1

    = 2.5x1500/750 = 2.5x2 = 5 atm
