How many gram of water is equal to 2.2 mol of water?
2.2 mol water = 2.2 (mol) * 18 (g/mol) water = 39.6 (mol*g/mol) = 40 g18 g/mol = mol mass of H2O = 2*H + 1*O = (2*1 + 16) g/mol
How do you find the molar mass of compounds like water?
The molar mass is the mass of one mole of a substance in g/mol. In order to determine the molar mass, you must know the chemical formula and have access to a periodic table. Let's use water as an example. The chemical formula for water is H2O. To find the molar mass, multiply the atomic weight on the periodic table in grams/mol for each element times the subscript for the element, and add the molar masses. H: 2 x 1.00794g/mol = 2.01588g/mol O: 1 x 15.9994g/mol = 15.9994g/mol ------------------------------------------------ Molar mass = 18.0153g/mol
What is the mass (in grams) of 1 mol H2O?
You calculate it by using Avogadro's number: 6.022 x10 23 which is one mole of substance. 1.00 x 1024 divided by 6.022 x 1023 = 10 divided by 6.022 = 1.661 mol H2O Use the molar mass of water (18.02 g mol-1) to get to the mass in grams. 18.02 g x 1.661 mol = 29.93 g H2O
How to convert 1.5 mol of water into grams?
First find the molar mass of water using the atomic mass of the elements that make up water (H2O) = (2x1.01g/mol+16g/mol) = 18.02 g/mol. Then we know 1mol water is 18.02g so we multiply 18.02g/mol H20 x 1.5mol H2O to get 27.03g but rounds to 27 because 1.5mols has two significant digits.
What is the mass of a sample containing 5.82 mol of zinc?
378.3g You multiply the RMM by the Concentration (mol) Mass(g)=Concentration(mol)*RMM
What the molar mass of water?
The molar mass of water is 18 g/mol.

What is the mass of 0.7891 mol of ferric oxide (Fe2O3)?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
What is the mass of 0.7891 mol of ferric oxide?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
What is the mass of 0.7891 mol of ferric oxide Fe2O3?
Atomic mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
What is the molar mass of sodium oxalate?
molar mass is 318 g/mol (2X27)+3(2X12+4X16)=318g/mol
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
What is the formula mass of CS2?
Formular mass is the sum of the atomic mass' of the corresponding elements. C = 12.011 g/mol S = 32.06 g/mol 12.011 g/mol + 2(32.06 g/mol)= 76.131 g/mol Therefore, the formula mass of CS2 is 76.131 g/mol.
