1.8 moles
To convert moles to grams, you need to use the molar mass of sodium. The molar mass of sodium is about 23 grams per mole. Therefore, 4.5 moles of sodium would be approximately 103.5 grams (4.5 moles * 23 grams/mole).
1 mole Na = 22.989770g 10 moles Na = 10 x 22.989770g = 229.89770g
62 grams a+
For this you need the atomic mass of Na. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.17.5 grams Na / (23.0 grams) = .761 moles Na
To determine the number of moles in 17.5 grams of sodium, you need to first calculate the molar mass of sodium (about 22.99 g/mol). Then, divide the given mass by the molar mass to find the number of moles. In this case, 17.5 grams of sodium is approximately 0.761 moles.
The answer is 0,25 moles.
22.98977 grams.
None. There is no hydrogen in sodium
40*4=160g
For this you need the atomic mass of Na. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.11.5 grams Na / (23.0 grams) = .500 moles Na
Mass of 2 moles of Na = 2 x atomic mass of Na = 2 x 23.0 = 46.0g
Since Na2O is a 1:1 ratio with Na, if 2.80 moles of Na react, 2.80 moles of Na2O will be produced. To convert moles to grams, we use the molar mass of Na2O (61.98 g/mol) to find that 2.80 moles of Na2O is equal to 2.80 moles * 61.98 g/mol = 173.50 grams of Na2O.
0.21705 moles. There are 22.9898 grams sodium in 1 mole.
To find the number of grams in 0.350 moles of Na, you need to multiply the number of moles by the molar mass of Na. The molar mass of Na is 22.99 g/mol. So, 0.350 moles of Na * 22.99 g/mol = 8.0465 grams of Na.
In 1 mol of NaCl there is 58.44 grams. ( 22.99 grams of Na + 35.45 grams of Cl). Using stoichiometry, you cancel the grams by taking 29.22 grams/58.44 grams. So 0.50 moles of NaCl
The molar mass of sodium is approximately 23 grams per mole. Therefore, 2 moles of sodium would weigh around 46 grams.
molar mass Na = 22.99g/mol (atomic weight in grams) 0.0135mol Na x (22.99g/mol) = 0.310g Na
