This depends on what element/molecule you're converting.
You use the molar mass. (The sum of Atomic Mass of all the elements you're using.) Divide .00336 (since that what I'm assuming you meant) by the molar mass.
For an example of one element, it would look like this:
.00336 grams of Carbon converted to moles.
Carbon's molar mass is approximately 12.
(.00336)/ (12) = 2.8 X10-4 (or .00028) moles.
For an example of a molecule, it would look like this:
.00336 grams of Ammonium Chloride converted to moles.
Ammonium: NH4
Ammonium Chloride: NH4Cl
N's molar mass: 14
H's molar mass: 1 (but there's 4 of them, so multiply by 4): 4.
Cl's molar mass: 35.45
Add them all together: 53.45
(.00336g)/53.45 = 6.29 x 10-5 (.0000629) moles.
An average pear weighs around 166 grams.
For this you need the atomic (molecular) mass of CO2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. CO2=44.0 grams454 grams CO2 / (44.0 grams) = 10.3 moles CO2
To find the number of moles in 1.1 grams of FeCl3, you'll first determine the molar mass of FeCl3 (55.85 + 35.45*3) = 162.31 g/mol. Then, divide the given mass (1.1g) by the molar mass to get the number of moles (1.1g / 162.31g/mol ≈ 0.007 moles of FeCl3).
To find the number of moles of CaBr2 in 5.0 grams, you first need to calculate the molar mass of CaBr2. The molar mass of CaBr2 is 200.8 g/mol. Divide the given mass by the molar mass to find the number of moles: 5.0 g / 200.8 g/mol = 0.025 moles of CaBr2. Since there is one mole of CaBr2 for every two moles of CaBr, you have half of that amount in moles of CaBr: 0.025 moles / 2 = 0.0125 moles of CaBr.
Using the formula number of moles = mass divided by molar massso mass = number of moles X molar massFind molar mass by adding up the masses of all the atoms in your substance.A good way to remember this is as the formula g/mw = moles, and the mnemonic for this is"Mine workers (mw= molecular weight) under ground (grams of compound you are dealingwith = Moles!
The number 2.20 moles of Sn equals 261.14 grams. This is a taught in biology.
1 mol of any element is the atomic weight expressed in grams.
Meaningless unless you specify the type of molecule.
For this you need the atomic (molecular) mass of KCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. KCl= 74.6 grams50.0 grams KCl / (74.6 grams) = .670 moles KCl
Molarity = moles of solute/Liters of solution. get moles KI 2.822 grams KI (1 mole KI/166 grams) = 0.017 moles KI ( 67.94 ml = 0.06794 Liters ) Molarity = 0.017 moles KI/0.06794 Liters = 0.2502 M KI
16 grams of oxygen how many moles is 0,5 moles.
mol = mass/Mr If the Mr and number of moles of a substance is known then the mass can be calculated. example:- if we have 1 mole of Na, how many grams do we have? mass = mol x Mr mass = 1 x 23 mass = 23g
The molar mass of gold is approximately 197 grams/mol. To convert moles to grams, you multiply the number of moles by the molar mass. Therefore, 2.8 moles of gold would be approximately 2.8 * 197 = 551.6 grams.
Find moles potassium iodide first.2.41 grams KI (1 mole KI/166 grams) = 0.01452 moles KIMolarity = moles of solute/Liters of solution ( 100 ml = 0.1 Liters )Molarity = 0.01452 moles KI/0.1 Liters= 0.145 M KI solution================
85.636 grams carbon (1 mole C/12.01 grams) = 7.1304 moles of carbon ---------------------------------
