Homework Answers
1)
We know , 1 bar = 750.062 mmHg
So, 750.062 mmHg = 1 bar
1 mmHg = 1 / 750.062 bar
689 mm Hg = 689 / 750.062 bar
= 0.918 bar
2)
Given that,
Pressure = 731 mmHg ( convert mmHg into atm )
= 731 / 760
= 0.961 atm

Which of the following statements about ideal gases is incorrect? At a constant pressure, when temperature increases, volume increases. O A gas with a larger molar mass will have a higher density Gas pressure is directly proportional to the number of moles of gas. At constant volume, when the temperature increases, pressure decreases. At a constant temperature, when the volume decreases, the pressure increases.
