The initial pressure is 4.0 atm and the initial volume is 30.0 mL. If the pressure is increased to 8.0 atm, what will be the new volume?

New volume, V2 = 15mL

Explanation:

Given the following data;

Initial volume, V1 = 30mL

Initial pressure, P1 = 4atm

New pressure, P2 = 8atm

To find the new volume V2, we would use Boyles' law.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

Substituting into the equation, we have;

V2 = 15mL

Therefore, the new volume is 15 mL.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
