The expression"molar mass" for sodium is not corresct. After today rules of IUPAc correct is atomic weight. The atomic weight of sodium is determined very exact: 22,989 769 28 (2013 data); the error is +/- 2 for the last digit of this value.

What is the mass in grams of 0.0135 mole of the element Na?
molar mass Na = 22.99g/mol (atomic weight in grams) 0.0135mol Na x (22.99g/mol) = 0.310g Na
The mass of a mole of a substance expressed in grams is called a?
molacular mass
How many grams of sodium are in a 1 mole sample of sodium?
The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.
What is the percent composition of Sulfur in Sodium sulfate?
% of A = (mass of A in 1 mole of the compound/Mass on one mole of the compound) x100Na + SO4 à Na₂SO₄Molar Mass of Na₂SO₄ = 142Molar Mass of S = 32% A = (32/142) x100= 22.6%
How is the molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
How many moles of Na are in 15 g of NaCl?
Molar Mass NaCl is 58.5g, 39.3% Na (5.90g), Molar Mass Na is 23.0g, 5.90/23.0 = 0.256 moles
How many grams of NaCl would you have if you had 3.7 moles of NaCl?
Molar mass of Na = 22.9898g/mol Molar mass of Cl = 35.45g/mol Total molar mass = 58.4398g/mol 58.4398g * 3.7mol =216.22726g
What is the mass in grams of 0.15 moles sodium?
Molar mass Na = 22.99g/mol0.15 mol Na = 0.15*22.99 = 3.45g
What is the mass in grams of 0.0135 mole of the element Na?
molar mass Na = 22.99g/mol (atomic weight in grams) 0.0135mol Na x (22.99g/mol) = 0.310g Na
Could you convert .10 mol of NaNO3 to grams?
#moles = mass/molar mass mass = #moles*molar mass mass = .10 moles*(atomic weight of na+atomic weight of N+3(atomic weight of oxygen)
What is the mass percent of sodium in Na2CO3 the molar mass of Na2CO3 is 106gmole?
If atomic masses, Na = 23 C=12, O = 16 Molar mass of Na2CO3 = (23x2) + 12 + (16 x 3) = 106 mass of Na in this compound = 2x23 = 46 Therefore percentage = 46 / 106 x 100 = 43.4%
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
The mass of a mole of a substance expressed in grams is called a?
molacular mass
How many atoms are in NaC1?
NaCl - you find the molar mass of Na (sodium) and add it to the molar mass of Cl (chlorine). This is one mole of NaCl. You then multiply it by Avogradro's number, which is 6.02 x 1023 and this will give you your answer.
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
How many atoms are in 14.500g Cr?
Use this fomula: (m/M)*NA in which m is mass in gram (g), M is molar mass (g/mol) and NA is the Avogadro number (mol^-1)
How do you find the mass of an atom with only the molar mass given?
Molar mass of an element is the atomic weight on the periodic table in grams. 1 mole of atoms of an element is 6.022 x 1023 atoms. To find the mass of one atom of an element, divide the element's molar mass by 6.022 x 1023 atoms.Example:Sodium, Na, has a molar mass of 22.989770g/mol (atomic weight in grams)1 mole Na atoms = 6.022 x 1023 atomsSolution:22.989770g/mol x 1mol/6.022 x 1023 atoms = 3.818 x 10-23g/atom
