Question - A mixture of gases contains 1.94 moles of O2, 2.87 moles of N2, and 0.92 moles of H2 at a total pressure of 10.00 atm. After 4.51 mol of H2 are added, what is the new total pressure? (*hint: adding H2 does not affect how many collisions O2 and N2 make with the container walls.) Give your answer in atm with 4 significant figures.
