5 dm' of dry hydrogen is collected at a temperature of 37 °C and 720 mm pressure. Find volume of gas at S.T.P.? ​

Answer 1

Answer:

5 dm3 of dry hydrogen is collected at the a temp. of 37c and 720 mm pressure. Find the volume of gas at STP?

Explanation:PV/T= P₁V₁/T₁

Here P= 750−14= 736mm, V=50cm³, T=17+273=290K,

P ₁ =760mm, T₁ =273K

then, V ₁ =

290×760

736×50×273

=45.58cm ³
