You divide by the molecular weight. This can be found on the Periodic Table by adding the atomic masses. (It's units are already grams per mole).
You have to first convert Kilos to grams. 1.42 kilos is 1420 grams. Next you have to find out the molecular weight (can be added up from the periodic table). Now divide grams by molecular weight to get your final answer in moles.
The answer is 902,45 g.
40.79 H2O kj/moles x 1 moles/18 grams= 2.266/1000=0.002266 joules/grams
Conversion of a certain mass of a substance to moles requires knowing the molar mass. Molar mass is given in grams per mole. Dividing the known mass by the molar mass gives the number of moles.
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
The answer is 1,54 moles.
How many molecules are in 94 grams of sodium fluoride
There are 29/14, or just over 2 moles of nitrogen in 19 grams.

The molar mass of a compound is expressed in grams.
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
Yes. You should convert grams to moles in order to use the ideal gas law. The units of the other variable, R (gas constant) has moles in it.
Actually, you can. You can convert grams to moles then moles to meters... or vise versa. usually the place of a mol is 1. unless you are good at chemistry.
52.1grams. moles = mass (in grams)/RMM (relative molecular mass) 1.3 moles = mass (in grams)/ 40.078 mass = 40.078 x 1.3 = 52.1grams
