How many formula units are in 3.6 grams of nacl?
Use stoichiometry. 3.5g-> moles 22.99+16+1.0079=39.99 Now 3.5/39.99 = .088 moles of NaOH Now you can use avagadros number 6.022x10^23 .088 moles -> formula units .088/6.022x10^23 You should end up with 1.46x10-25 formula units. Yeah, I know, Chem sucks huh?
What is the gram formula mass for Ca3PO42?
Ca = 40 x 3 = 120 grams P = 31 x 2 = 62 grams O = 16 x 8 = 128 grams Add them together and you have 310 grams. This is the mass in grams of your formula. It is expressed in grams/mole because 310 is the weight of one mole of Ca3(PO4)2.
What is the formula mass of h20?
H: 1 g/mol O: 16 g/mol H x 2 = 2 g/mol O x 1 = 16 g/mol 2 g/mol + 16 g/mol = 18 g/mol
How many moles of carbon atoms are there in 3 grams of carbon?
The questions asks how many moles of carbon atoms.Molar mass is defined as the mass of one mole of a substance or in this case 6.022x1023 atoms of carbon. So the molar mass for carbon is 12.0 g/mol. Therefore the number of moles of carbon atoms is just 36/12.0 = 3.0 moles of carbon.How many atoms are in 36 grams of Carbon?[36 (gC) /12.0 (gC/molC)] * 6.02*10+23 (atoms C/molC) = 1.8*10+24 atoms in 36 g Carbon
How many moles of ozone O3 could be formed from 96.0g of oxygen gas O2?
A) 0.500 mol B) 1.000 mol C) 2.00 mol D) 3.00 mol E) 1/16 mol
How many grams of oxygen are in 16.0g of fructose?
16.0 g Fru = [16 (g) / 180 (g/mol Fru)] * [6 (mol O) / 1 (mol Fru)] * 16 (g O)/mol O) = 8.53 g O
It takes point 16 g of helium He to fill a balloon How many grams of nitrogen N2 would be required to fill the balloon to the same pressure volume and temperature?
PV=nRT if you are fixing PV and T then the question really is how many moles of Helium is 16 g. Take that number of moles and multiply by the molecular weight of Nitrogen (28.02 g/mol) to get the number of grams of N2 needed. 16 g/4.00g per mol = 4 mol He X 28.02 g/mol = x g of N2 needed.
How many grams of O2 are in 50moles of the oxygen gas?
Ar of O = 16g/mol Mr of O2 = 2(16) = 32g/mol Using the formula : mass = Mr x number of moles mass = 32g/mol x 50mols = 1600g
How many grams does 3 moles of CO2 weigh?
Atomic mass of C = 14g/mol Atomic mass of O = 16g/mol Molecular mass of CO2 = 12 + 2(16) = 44g/mol mass = number of moles x molecular mass mass = 3 mol x 44g/mol = 132g
Molar mass of oxygen?
16 grams or 32 grams, depending on what you're looking at.The mass of one mole of oxygen atoms is about 16 grams, but oxygen gas exists as a molecule (O2) so 1 mole of (O2) is 32 grams.
How many moles are there in 6.5 grams of CO2?
6.5 grams CO2 divided by 44 grams CO2 per mole CO2 = 6.8 mole CO2 (Molar mass CO2 = 12 + 2*16 = 44 g/mol)
What is the mass of oxygen in grams?
15.994 grams/mol, but it can rounded to 15.99 or 16.0 g/mol.
How many formula units are in 3.6 grams of nacl?
Use stoichiometry. 3.5g-> moles 22.99+16+1.0079=39.99 Now 3.5/39.99 = .088 moles of NaOH Now you can use avagadros number 6.022x10^23 .088 moles -> formula units .088/6.022x10^23 You should end up with 1.46x10-25 formula units. Yeah, I know, Chem sucks huh?
How many meqs are in nacl tabs?
about 16 mEq
What is the mass of 3 mol of Al?
As the periodic table of Elements states, Al has a Molar Mass (Grams/Mole) of 27.0g/mol. So 3 mols of Al mass is the same as 3 times 27.0g/mol. So, the equation is as follows: 3mols x 27.0g/mol = 81.0g. The reason on why it ends with grams is because the unit of moles in 3 will cancel out with the unit of mols in 27.0g.
How many ounces are 16 grams?
16 grams = 0.5644 ounces
How many pounds is 16 grams?
16 grams is 0.035274 pounds.
