Question

5) A sample of hydrogen has an initial temperature of 50.° C. When the temperature is
lowered to -5.0° C, the volume of hydrogen becomes 212 cm'. What was the initial
volume of the hydrogen in dm?​

Answer 1

Answer:

Using Ideal gas laws,          

V₁ T₂ = V₂T₁    where T=temperature in Kelvin, V=volume in dm³

V₁ x (50+273) = 212/1000 x (-5+273)

V₁ = 56.816/323

V₁ = 0.178 dm³
