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

1.53 L.

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,

Hence, the volume at STP is 1.53 L.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
