Hello,
From the Ideal Gas equation,
P V = n R T = ( given mass, w / molar mass, m ) R T
1 × V = ( 12 / 120 ) × R × (273+t) ----- (i)
1.1 × V= ( 12 / 120 ) × R × ( 273 + t + 10 ). ----- (ii)
Dividing equation (ii) by equation (i), we get
1.1 = (273+t+10) / ( 273+t+)
or t = −173 degree Celsius
I hope you find the answer helpful.
Thank you.
