Question

What would the volume of gas be at 150 c if it had a volume of 693 ml at 45 c​

Answer 1

`\boxed{\text{922 mL}}`

Step-by-step explanation:

The pressure is constant, so we can use Charles' Law to calculate the volume.

`(V_(1))/(T_(1)) = (V_(2))/(T_(2))`

Data:

V₁ = 693 mL; T₁ = 45 °C

V₂ = ?; T₂ = 150 °C

Calculations:

(a) Convert temperature to kelvins

T₁ = ( 45 + 273.15) = 318.15 K

T₂ = (150 + 273.15) = 423.15 K

(b) Calculate the volume

`( 693)/(318.15) = ( V_(2))/(423.15)\\\\2.178 = ( V_(2))/(423.15)\\\\V_(2) = 2.178 * 423.15 = \boxed{\textbf{922 mL}}`
