Question

What volume will 250. mL of gas at STP occupy ig the pressure changes to 2.0 atmospheres and the temperature changes at 30 degrees Celsius

Answer 1

Answer:

it is 75 degrees

Explanation:

Answer 2

Volume is 138.7 mL.

The equation for calculation of volume is as follows:-

$\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}$

STP:-

Temperature=273 K

Pressure=1 atm

$\frac{1 atm\times250mL}{273 K} =\frac{2 atm\times V_2}{303\ K}\\V_2=138.7\ mL$

Hence, the volume is 138.7 mL.
