Answer: The final pressure is 0.81 kPa

Explanation:

The combined gas equation is,

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

where,

$P_1$ = initial pressure of gas = 0.58 kPa

$P_2$ = final pressure of gas = ?

$V_1$ = initial volume of gas = v

$V_2$ = final volume of gas = $v-\frac{40}{100}\times v=0.6v$

$T_1$ = initial temperature of gas = $25^0C=(25+273)K=298K$

$T_2$ = final temperature of gas = $-22^0C=(-22+273)K=251K$

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

$\frac{0.58\times v}{298}=\frac{P_2\times 0.6v}{251}$

$P_2=0.81kPa$

The final pressure is 0.81 kPa

Calculate the molar mass of a gaseous substance if 0.125 g of the gas occupies 93.3 mL at STP.

just olya [345]

Answer:

30.0g/mol

Explanation:

Step 1: Given data

Mass of the gas: 0.125 g

Pressure (P): 1 atm (standard pressure)

Temperature (T): 273.15 K (standard temperature)

Volume (V): 93.3 mL

Step 2: Calculate the moles of the gas

We will use the ideal gas equation.

$P \times V = n \times R \times T\\n = \frac{P \times V}{R \times T} = \frac{1atm \times 0.0933L}{\frac{0.0821atm.L}{mol.K} \times 273.15K} = 4.16 \times 10^{-3} mol$

Step 3: Calculate the molar mass of the gas

4.16 × 10⁻³ moles correspond to a mass of 0.125 g. The molar mass of the gas is:

$\frac{0.125g}{4.16 \times 10^{-3} mol} =30.0g/mol$
