Question

1) A volume of 10.00 L pure liquid H2O at 90.0

A volume of 10.00 L pure liquid H2O at 90.0 degree C has a specific gravity of 1.036. What is the mass (in kg) of this system? Show you calculations using a single dimensional equation. Calculate the molar fractions of the components in a gas mixture of equal amounts by mass of nitrogen and chlorine? A rupture disk is at the bottom of a tank filled with cyclopentane (see Figure). It is rated to break when 25 psig is applied to the disk. What height of cyclopentane in the tank will cause this disk to rupture?

Explanation / Answer

1) mass = volume* density = (10*10^-3 m^3)*(1.036*1000 kg/m^3) = 10.36 kg....

2) let the mass be x, thefore molar fraction = (m/28)/(m/35.5) = 1.268...

c) pressure = density*g*h, here pressure = 25 psig =172368.932 Pa, density = 751.00 kg/m
