Question

0°C in 101.3 K PA pressure a sample of gas occupies 30 mL if the temperature is increased to 30°C in the entire gas sample is transferred to a 20 mL container what will be the gas pressure inside a container

Answer 1

Answe 174.0 KPA

Step-by-step explanation:

0°C in 101.3 K PA pressure a sample of gas occupies 30 mL if the temperature is increased to 30°C in the entire gas sample is transferred to a 20 mL container what will be the gas pressure inside a container

PV=nRTt

so

n = PV/RT

P = 101.3 KPA

T = 0+273.2 = 273.200

V = (30/1000) L = 0.03 L

R =0.082

SO

n= (101.3 X 0.03)/(0.082 X 273.2)

= 0.14 moles

PV= nRT

N= 0,14

T = 30 + 273.2= 303.2

V= (20/1000)L =0.02L

since PV = nRT

THEN

P=nRT/V

so

P=(0.14 X 0.082 X 303.2)/0.02 =

174.0 KPA
