Answer:

207.24.

Explanation:

The mass numbers of the 4 isotopes are  82+ 122 = 204,  82 + 125 = 207,

82 + 124 = 206 and 208.

The approximate atomic mass  is worked out by adding the products of their relative abundances  and mass numbers:

0.014*204 + 0.221*207 + 0.241*206 + 0.524*208

= 207.24.

Which step will decrease the pressure of a gas inside a closed cubical container? increasing the number of moles of gas decreasi
Jobisdone [24]

Answer: Decreasing the temperature inside the container will decrease the pressure of a gas inside a closed cubical container.

Explanation:

According to Gay-Lussac's Law : 'The pressure of the gas increases with increase in temperature of the gas when volume of the gas is kept constant'.

(Pressure)\propto (Temperature)

At constant volume, pressure of the gas will decrease on decreasing the temperature or vice versa.

Decreasing the temperature inside the container will decrease the pressure of a gas inside a closed cubical container.
