Question

If 153.48 mL of hydrogen is collected at 14.0 degrees C and 973 kPa, what will be its volume at STP?

Answer 1

1.53 L.

Step-by-step explanation:

Given,

Volume pf hydrogen, V₁ = 153.48 mL = 0.15348 L

Temperature, T₁ = 14°C = 273+14 = 287 K

Pressure,P₁ = 973 kPa

1 atm = 101.325 kPa

973 kPa = 9.60 atm

At STP

P₂ = 1 atm

T₂ = 25° C = 273+25 = 298 K

V₂ = ?

Now,

`(P_1V_1)/(T_1)=(P_2V_2)/(T_2)`

`(9.60* 0.15348)/(287)=(1* V_2)/(298)`

`V_2 = 1.53\ L`

Hence, the volume at STP is 1.53 L.
