Sodium has an Atomic Mass of 22.99. Therefore 1 mole of it weighs 22.99 grams. Similarly a mole of bromine weighs 79.9 grams.
A mole of sodium bromide - NaBr - contains 1 mole each of sodium and bromine (note that this is not true for all chemical salts) and so 1 mole of it weighs 102.89 grams.

∙ 12y agoOne mol of sodium chloride has a mass of 58.443 grams. This is calculated by adding the molecular weight of each component of sodium chloride. Sodium chloride has a formula of NaCl. This means that one molecule of sodium chloride has one sodium atom and one chlorine atom. The molecular weight of the sodium portion of the molecule is 22.9898 grams/mol and the molecular weight of the chlorine part of the molecule is 35.4532 grams/mol. Add the two together to get the mass of 1 mol of sodium chloride.

∙ 10y agoThe formula unit of sodium fluoride is NaF. Its molar mass is 41.998g/mol. You can know this because one formula unit of NaF has one Na atom and one F atom. The molar mass of each element is its atomic weight in grams. To determine the mass of one mole of NaF, or molar mass, you add the molar masses of Na and F.

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%
What is the mass of 9 moles of sodium?
1 mole Na = 22.989770g 9 mol Na x 22.989770g/mol = 206.9g Na = 200g Na rounded to one significant figure
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

How is a mole related to the atomic mass?
The atomic mass, in grams, is the mass of one mole of atoms.
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 number of grams in 0.350 mole of Na is?
1 mol of Na+ = 22.989g Na+(0.350 mol) x (22.989 g/mol) = 8.05 g Na+
