How many mol water do you have in 9.34g? mol = 9.34g * 18. 015 = 0.5184 mol H2O Number of molecules = 0.5184 * 6.022 *10²³ =... show more
Best answer: There are 2 things that you need to know - or that you can look up :
Molar mass of H2O = 18.015 g/mol
1 mol of anything contains 6.022*10²³ particles - in this case - molecules.
How many mol water do you have in 9.34g?
mol = 9.34g * 18. 015 = 0.5184 mol H2O
Number of molecules = 0.5184 * 6.022 *10²³ = 3.12*10²³ molecules.

Oh, sure. You just light this magical plant on fire, and breathe it in, and it gives you magical psychoactive effects. THC is just magic, man. Absolutely nothing going on with receptors, or dopamine, or anything else like that.

• ### Why does mass not affect pressure in ideal gases?

It would seem logical that the pressure exerted would increase if the gas particles’ mass becomes greater. For example, at constant temperature, volume, and number of moles, why does hydrogen exert the same amount of pressure as oxygen when oxygen is clearly a lot heavier? Is it because the effect of mass is so... show more

For example, at constant temperature, volume, and number of moles, why does hydrogen exert the same amount of pressure as oxygen when oxygen is clearly a lot heavier? Is it because the effect of mass is so small we simply ignore it altogether?

Best answer: Hemp oil is just a type of vegetable oil. It can be used like many other vegetable oils in recipes (though best to not heat it) or on your skin or hair as a moisturizer. Like most foodstuffs, it seems to have some health benefits (fatty acids that are good for you) and some potential health risks.

CBD oil is the purified form of cannabidiol . It's a medicine (available over the counter in most places where it is legally available at all) , used primarily for pain relief. If you have cancer pain and are considering using it for pain relief, you would still want to talk to your doctor about it. (There are pros and cons to everything and even OTC meds have risks and may not be safe or appropriate for all patients.)
