Answer: B) 8.25 atm.
Explanation: Absolute pressure is the sum of gauge pressure and atmospheric pressure.
[tex]P_a_b_s_o_l_u_t_e=P_g_a_u_g_e+P_a_t_m_o_s_p_h_e_r_e[/tex]
Atmosphere pressure is given as 9.25 atm and the atmospheric pressure is 1.00 atm.
Let's plug in the values in the above formula:
9.25 atm = [tex]P_g_a_u_g_e[/tex] + 1.00 atm
[tex]P_g_a_u_g_e[/tex] = 9.25 atm - 1.00 atm
[tex]P_g_a_u_g_e[/tex] = 8.25 atm
So, gauge pressure inside the container is 8,25 atm and hence the right option is B.
