4.828gNa X (1 mole/22.989gNa) = .21
22.989 = atomic weight of Na
To find the number of moles of sodium sulfate in 284 g, you need to divide the given mass by the molar mass of sodium sulfate. The molar mass of sodium sulfate (Na2SO4) is 142 g/mol. So, 284 g / 142 g/mol = 2 moles of sodium sulfate.
molecular formula for sodium chloride = NaClIf the mole (n) for NaCl = 5.3 moles, then the mole of sodium (Na) = 5.3 moles as well. 1 to 1 ratio mass = moles X molar mass m = 5.3 x 22.9 = 121.37 grams of sodium in 5.3 moles of sodium chloride
There are 3 moles of sodium represented in one mole of sodium phosphate (Na3PO4). This is because the subscript 3 in Na3PO4 indicates that there are 3 sodium ions for every molecule of sodium phosphate.
To find the number of sodium atoms in 0.2310 g of sodium, you need to convert the mass to moles using the molar mass of sodium (22.99 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. This calculation will give you the number of sodium atoms present in 0.2310 g of sodium.
To find the number of moles in 585 g of sodium chloride, we first need to determine the molar mass of NaCl. Sodium has a molar mass of approximately 23 g/mol, and chlorine has a molar mass of approximately 35.5 g/mol. Adding these together gives a molar mass of approximately 58.5 g/mol for NaCl. Dividing the given mass (585 g) by the molar mass gives us approximately 10 moles of sodium chloride.
55.0 moles of sodium are equal to 1 264,44 g.
To find the number of moles in 46.0 g of sodium, you need to divide the given mass by the molar mass of sodium. The molar mass of sodium (Na) is 22.99 g/mol. Thus, 46.0 g ÷ 22.99 g/mol = 2 moles of sodium.
1 g of sodium sulfite is equivalent to 0,0079 moles.
0,40 moles of sodium chloride contain 23,376 g.
5 moles of carbon is 60,055 g.5 moles of sodium is 114,949 g.
To find the number of moles of sodium sulfate in 284 g, you need to divide the given mass by the molar mass of sodium sulfate. The molar mass of sodium sulfate (Na2SO4) is 142 g/mol. So, 284 g / 142 g/mol = 2 moles of sodium sulfate.
The molar mass of sodium is 22.99 g/mol. Therefore, the mass of 8 moles of sodium would be 8 moles x 22.99 g/mol = 183.92 g.
10 moles of sodium chloride have 584,397 g.
Sodium reacts with water. 0.652 NaOH moles will form.
8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
To determine the number of moles in 20g of sodium hydroxide, you need to divide the given mass by the molar mass of sodium hydroxide. The molar mass of NaOH is 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). So, 20g NaOH / 40 g/mol = 0.5 moles of sodium hydroxide.
To find the number of moles in 46g of sodium, you need to divide the mass of the sample by the molar mass of sodium (22.99 g/mol). The calculation is 46g / 22.99 g/mol = approximately 2 moles of sodium.
