Question

How many moles of gas are in a container with a volume of 9.55 mL at 35 °C and a pressure of 895 mmHg?

Answer 1

Step-by-step explanation:

Pressure P = 895 mm of Hg

895/760 atm

= 1.1776 atm

Temperature T = 35 + 273 = 308 K

volume V = 9.55 mL

9.55 x 10⁻³ L

Value of R = .082 Litre-atm/mol.K

Putting the value in gas equation

`(PV)/(RT) =n` , n is no of moles of gas.

`(1.1776*9.55*10^(-3))/(.082*308) =n`

= .4453 x 10⁻³ moles .
