How is molar mass of an element used to convert form number of moles to mass in grams?
The molar mass of an element indicates how much mass is in one mole of the element. From that we can make a ratio to convert moles of a substance to mass in grams.
For example: How many grams are in 3.54 moles of oxygen?
You find on the Periodic Table that the molar mass of oxygen is 16.00. This means that there are 16.00 grams in 1 mole of oxygen.
From this, we can make a ratio:
16.00 g / 1 mol O. Now we can use it to convert mol to g by multiplying the given amount of moles by , keeping in mind that we want to cancel the mol unit. To do that, we keep the mol unit in the denominator of the ratio.
3.54 mol O x 16.00 g = 56.64 g
1 mol
* remember to follow the rules of significant figures! We're given 3.54 moles, which has 3 sig figs. In the entire problem, 3.54 has the least sig figs, so the answer must contain 3 significant figures: 56.6 g

Which mathematical relationship should you use to convert moles of a substance into grams?
You can use the molar mass of the substance to convert moles into grams. This involves multiplying the number of moles by the molar mass of the substance, where the molar mass is expressed in grams per mole. This relationship allows you to convert between the two units.
How do you convert 5.2 moles of lead to grams?
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!
How do you convert 3 moles of NaC2H3O2 to grams. the numbers after the letters are suppose to be subscripts?
Use the molar masses for sodium (23g/mol) carbon (12g/mol), hydrogen (1g/mol) and oxygen (16g/mol). Add them together in the amounts indicated by the subscripts. Multiply the 3mol by this number and you have your mass in grams!(values are approximate, a good chemistry textbook will have more accurate values).
How do you convert from number of particles to moles?
You must first calculate the molar mass of the substance. To do so, you add up the molar masses of all the elements that make up the compound, multiplied by the number of atoms of that element in one molecule of the substance. For example, AgNO3 has a molar mass of about 169.8 amu. In one molecule of AgNo3, there is one atom of Silver (molar mass 107.8), one atom of Nitrogen (molar mass 14), and three atoms of Oxygen (molar mass 16). Multiply the molar mass of Silver by the number of Silver atoms (1), multiply the molar mass of Nitrogen by the number of Nitrogen atoms (1), multiply the molar mass of Oxygen by the number of Oxygen atoms (3), add the numbers up and you have the molar mass of the substance (169.8). Step 2 is easy. To convert from grams to moles, you divide the number of grams by the molar mass (units for molar mass are grams per mole, so dividing by molar mass cancels the grams). To convert from moles to grams, you multiply by the molar mass.
What is the formula to convert moles to grams?
There is no 'formula' of a mole. A mole is a number of atoms or molecules or electrons (or anything, but it's usually used in chemistry) equal to 602200000000000000000000 (that is supposed to be 20 zeros after 6022). The number is usually written as 6.022 * 1023.
How do you convert an element to 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 : )
How is the number of moles of an element determined froma known mass?
To determine the number of moles of an element from a known mass, you use the element's molar mass (grams per mole). Simply divide the given mass of the element by its molar mass to calculate the number of moles. This relationship is described by the formula: moles = mass (g) / molar mass (g/mol).
How do you convert atoms to grams with Avogadro's number?
divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.
How to convert grams to atoms?
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.
How do you convert from grams to atoms and from mass to atoms?
To convert from grams to atoms, you need to use Avogadro's number (6.022 x 10^23 atoms/mol) to convert the given amount of substance into moles and then multiply by Avogadro's number to get the number of atoms. To convert from mass (in grams) to the number of atoms, first find the molar mass of the substance, then divide the given mass by the molar mass to get moles, and finally multiply by Avogadro's number to obtain the number of atoms.
How do I convert molar concentration to grams?
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
Convert grams to moles?
To convert grams to moles, you need to know the molar mass of the substance. Divide the given mass in grams by the molar mass to find the number of moles. This calculation is done using the formula: moles = grams / molar mass.
How do you calculate the grams of an element in a specific amount of a compound?
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
How many grams are there in 7.4 x10 to the 24th power atoms of silver?
To convert atoms to grams, you need to know the molar mass of the element. The molar mass of silver is 107.87 g/mol. First, calculate the number of moles in 7.4 x 10^24 atoms by dividing by Avogadro's number (6.022 x 10^23). Then, multiply the number of moles by the molar mass of silver to get the mass in grams.
How many grams are in 4.1 X 1022 molecules of N2I6?
To calculate the number of grams in 4.1 x 10^22 molecules of N2I6, you first need to find the molar mass of N2I6. Then, use this molar mass to convert the number of molecules to grams using Avogadro's number and the formula: grams = (number of molecules) / (Avogadro's number) * molar mass.
