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
For this you need the atomic mass of Na. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.1 moles Na Ã— (23.0 grams) = 48.3 grams Na
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
Mass of 2 moles of Na = 2 x atomic mass of Na = 2 x 23.0 = 46.0g
molecular mass of sodium hydroxide (NaOH) = 23(Na)+16(O)+1(H) =40 mass = (150 x 40)g =6000g
1 mole Na = 22.989770g 10 moles Na = 10 x 22.989770g = 229.89770g
how many moles are in 5.6 grams of Na?
Molar mass Na = 22.99g/mol0.15 mol Na = 0.15*22.99 = 3.45g
#moles = mass/molar mass mass = #moles*molar mass mass = .10 moles*(atomic weight of na+atomic weight of N+3(atomic weight of oxygen)
mol = mass/Mr If the Mr and number of moles of a substance is known then the mass can be calculated. example:- if we have 1 mole of Na, how many grams do we have? mass = mol x Mr mass = 1 x 23 mass = 23g
.391 moles of Na in NaCL
The atomic mass of sodium, Na is 23.0 Amount of Na = 454/23 = 19.7mol
The atomic weight of Na is 23.0 g/molTo convert moles to grams:grams Na = 2.04 mol Na23.0 g = 46.9 g Na1 molMultiply by grams per mole. Moles cancel out.
Atomic mass of Na is 23.0. This means that the mass of 1 mole of sodium is 23.0g. Mass of 4.5mol of Na = 4.5 x 23.0 = 103.5g
The answer is 0,25 moles.
2 * [(Na=23) + (Cl=35.5)] = 117 grams NaCl
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.
The atomic mass of sodium, Na is 23.0 Amount of sodium = mass of sample / atomic mass = 120/23.0 = 5.22mol
3 moles Na2CO3 (2moles Na/1mole Na2CO3)(22.99 grams Na/1 mole Na) = 138 grams of sodium
Atomic mass of Na: 23.0 grams1.50 moles × (6.02 × 1023 atoms) = 9.03 × 1023atoms
1 mole of sodium is 23 g, moles = mass/mole mass 35 g Na = 35/23 moles, = 1.5217 moles.
2.35 mol Na X (grams Na / 1 mol Na) = grams Na the element's amu on your periodic table is the amount of grams in one mole of that element.
Sodium is a metal element. Mass of 3.8 moles is 87.4g.
Molar Mass NaCl is 58.5g, 39.3% Na (5.90g), Molar Mass Na is 23.0g, 5.90/23.0 = 0.256 moles
The mole of a metal, such as sodium, is generally assumed to consist of Avogadro's Number of single atoms. The gram atomic mass of sodium is 22.9898. The number of moles in 120 grams of Na is therefore 120/22.9898, or 5.22, rounded to the justified number of significant digits.
