Take atomic mass or molar mass
of Al =27
Dalton thought that atoms were indivisible particles. But Thomsons discovery of the electron proved that the subatomic particles exist.
Answer:
Ki = 30atmL
Kf = 30atmL
Explanation:
The following data were obtained from the question:
V1 (initial volume) = 15.0L
P1 (initial pressure) = 2atm
V2 (final volume) = 7.5L
P2 (final pressure) = 4atm
Ki (initial constant) =?
Kf (final constant) =?
Boyle's law states that PV = K
Ki = P1V1
Ki = 2 x 15 = 30atmL
Kf = P2V2
Kf = 4 x 7.5 = 30atmL
Since Ki and Kf are the same, the gas obey Boyle's law
CaBr₃ = 40 + 80 * 3 = 280 g/mol
hope this helps!
