Mass = 5 g

volume = 20 cm³

density = mass / volume

therefore:

D = m / V

D = 5 / 20

D = 0.25 g/cm³

inn [45]

Answer:

8.125 atm

Explanation:

Hello,

Boyle's law states that at constant temperature:

P_1V_1=P_2V_2

In this case:

P_1=1 atm, V_1=27.3L, V_2=3.36L

Solving for P_2:

P_2=\frac{P_1V_1}{V_2}=\frac{1atm*27.3L}{3.36L}\\P_2=8.125atm

Best regards!
