How to Calculate the Molar Mass Now it’s high time to get closer to science. If you’ve been assigned to calculate the molar mass of a certain compound, you can actually use the periodic table as well as the amount of the given compound. Let’s recall the fact that the molar mass ...
To calculate ##v_1##, we use the speed distribution of the chamber (not the one coming out of the oven!) [tex]g = 2\alpha_2^2 v^3 exp(-\alpha_2 v^2)[/tex] [tex]v_1 = 2\alpha_2^2 \int_0^{\infty} v^4 exp(-\alpha_2 v^2)[/tex] [tex] =...
A sample of oxygen gas (O2) effuses 2.1 times faster than a hypothetical gas. What is the molecular weight of this gas (in g/mol)? Do not try to identify the gas. A gas has a density of 1.54 g/L at 1.14 atm and 15 ^oC. How to calculate the molar mass of the gas?
Now that the head is effectively detached, you can weigh the rest of the body and calculate the difference. Fermi's Method: By all means you can consider the head to be a sphere with radius $r=0.1$ meters. The density of head is more than water $\left( {10}^3 \frac{\ma...
