Answer #1

answer : A) 2.08 atm

explanation:

just convert all pressure into atm

760 mmHg = 1 atm

760 torr = 1atm

He pressure = 490 mmHg = 490 / 760 atm

                     = 0.645 atm

N2 pressure = 0.750 atm

Ne pressure = 520 torr

                        = 0.684 atm

total pressure = 0.684 + 0.750 + 0.645

                         = 2.08 atm
