How many moles of CO2 exert a pressure of 2.34atm at a volume of 25.6L and a temperature of 305k?

2.39 moles

Explanation:

From the question given above, the following data were obtained:

Pressure (P) = 2.34 atm

Volume (V) = 25.6 L

Temperature (T) = 305 K

Number of mole (n) =?

NOTE: Gas constant (R) = 0.0821 atm.L/Kmol

The number of mole of CO₂ can be obtained by using the ideal gas equation as shown below:

PV = nRT

2.34 × 25.6 = n × 0.0821 × 305

59.904 = n × 25.0405

Divide both side by 25.0405

n = 59.904 / 25.0405

n = 2.39 moles

Thus, the number of mole of CO₂ is 2.39 moles.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
