Answer 1

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

Answer 2

Answer:

4.17

Explanation:

P1= 720 mm

V2 = 5 dm3

T1= 310 k

P2 = 760 mm

V2 = ?

T2 = 273 k

P1*V1/T1 = P2*V2/T2

720*5/310 = 760*V2 /273

11.612 = 2.783

V2 = 11.612/2.783

V2 = 4.172
