Determine the ratio of the rates of effusion of helium and carbon tetrachloride molecules. The maximum pressure that the cylinder can withstand is 1310 mmHg. How many grams of helium must be added to the tank to reach its maximum pressure?

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

answer by yourhope:

how do models compare to real-world objects?

the answer is a and have a great day

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
