Artist 52 [7]

The answer is "C" because all isotopes have a different mass number. The number of protons does not change. The mass of electrons is negligible. Thus, the number of neutrons changes.

A 6.87-L sample of gas has a pressure of 0.732 atm and a temperature of 95 °C. The sample is allowed to expand to a volume of 9.
Jlenok [28]

Answer: The new pressure of the gas, assuming that no gas escaped during the experiment is 0.470 atm

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 0.732 atm

P_2 = final pressure of gas = ?

V_1 = initial volume of gas = 6.87 L

V_2 = final volume of gas = 9.22 L

T_1 = initial temperature of gas = 95^oC=273+95=368K

T_2 = final temperature of gas = 44^oC=273+44=317K

Now put all the given values in the above equation, we get:

\frac{0.732\times 6.87}{368}=\frac{P_2\times 9.22}{317}

P_2=0.470atm

Thus the new pressure of the gas, assuming that no gas escaped during the experiment is 0.470 atm
