Answer: 201 mL
Step-by-step explanation:
Initial volume V1 = 268 mL
Initial pressure P1 = 0.6 atm
Final volume of the gas V2 = ?
Final pressure of the gas P2 = 0.8 atm
Since, pressure and volume are involved while temperature is constant, apply the formula for Boyle's law
P1V1 = P2V2
0.6 atm x 268 mL = 0.8 atm x V2
160.8 atm mL = 0.8 atm x V2
V2 = (160.8 atm mL / 0.8 atm)
V2 = 201 mL
Thus, the final volume of the hydrogen gas will be 201 mL
