Video transcript

Welcome back everybody. We are told that the mass of a given molecule of a substance is 1.297 times 10 to the negative 22nd rams. And we are asked to calculate the molar mass of The substance. Well, the formula for the molar mass of the substance is simply just avocados number times the mass of a single molecule. So let's go ahead and plug in those numbers here we have that our molar mass is equal to six oh, sorry, let me erase that here real quick 6.22 times 10 to the 23rd times 1.297 times 10 to the negative 22nd. Which gives us a final answer of 78. g per mole corresponding to our final answer. Choice of E. Thank you all so much for watching. Hope this video helped. We will see you all in the next one.

At an altitude of 11,000 m (a typical cruising altitude for a jet airliner), the air temperature is -56.5°C and the air density is 0.364 kg/m^3 . What is the pressure of the atmosphere at that altitude? (Note: The temperature at this altitude is not the same as at the surface of the earth, so the calculation of Example 18.4 in Section 18.1 doesn't apply.)
