The desired outcome is the manipulation of moles to grams. Therefore, we need a conversion factor with these units. Molar masses have these units, so we begin by determining the molar mass of the compound. This is done by adding the molecular weights of the constituent elements, which are the numbers on the bottom of the entry of each element of most periodic tables. In mathematical notation:
M(Na2SO3)=M(Na)+M(Na)+M(S)+M(O)+M(O)+M(O)
or
M(Na2SO3)=2*M(Na)+M(S)+3*M(O)
Thus, for sodium sulfite, we get M=126.043 g/mol.
The next step is manipulation of our given quantity into our desired units. Through dimensional analysis, we can see that multiplication will do the trick here, so
10 mol Na2SO3 *126.043 g/mol = 1260.43 g Na2SO3

How many moles are in 4.5 x 10-3 g of sodium carbonate?
Dividing by the molar mass of sodium carbonate, we deduce that there are 4.25 x 10-5 moles in 4.5 x 10-3 grams of sodium carbonate.
How many grams of NaCl are present in 10.00 moles?
10 moles of sodium chloride have 584,397 g.
How many oxygen atoms in 5 g of sodium dichromate?
Sodium dichromate (Na₂Cr₂O₇) has seven oxygen atoms per formula unit. To determine the number of moles in 5 g of sodium dichromate, we first calculate its molar mass, which is approximately 261.97 g/mol. This means there are about 0.019 moles of sodium dichromate in 5 g. Since each mole contains 7 moles of oxygen atoms, the total number of oxygen atoms is about 0.019 moles × 7 × 6.022 × 10²³ atoms/mole, which equals approximately 7.98 × 10²² oxygen atoms.
How many atoms of each type are present in 143g of washing soda?
Washing soda, or sodium carbonate (Na2CO3), consists of sodium (Na), carbon (C), and oxygen (O). In 143 grams of washing soda, there are approximately 2 moles of Na2CO3 (since its molar mass is about 106 g/mol). This means there are 4 moles of sodium atoms (2 from each formula unit), 2 moles of carbon atoms, and 6 moles of oxygen atoms (3 from each formula unit). In terms of atoms, this corresponds to about 2.41 x 10²⁴ sodium atoms, 1.20 x 10²³ carbon atoms, and 3.61 x 10²⁴ oxygen atoms.
How many moles are there in 8.50 Molecules or sodium sulfate?
To convert molecules to moles, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) molecules per mole. Therefore, to find the number of moles in 8.50 molecules of sodium sulfate, you calculate ( \frac{8.50 \text{ molecules}}{6.022 \times 10^{23} \text{ molecules/mole}} ), which gives approximately (1.41 \times 10^{-23}) moles of sodium sulfate.

How many atoms of sodium are present in 3 moles of sodium and what is mass of it?
each mole contains 6.022*10(raised to the power 23) so three moles of sodium contain 18.066*10(raised to the power 23) mass of one mole of sodium is 11 grams so mass of three moles of sodium is 33 grams
How many moles are in 10 grams in sodium phosphate?
To calculate the number of moles in 10 grams of sodium phosphate (Na3PO4), we first need to determine the molar mass of Na3PO4, which is approximately 164.0 g/mol. Then, we can use the formula: moles = mass / molar mass. Therefore, for 10 grams of sodium phosphate, there would be approximately 0.061 moles present.
What conversion factor for sodium is used to change mass to moles is?
The conversion factor for sodium is its molar mass, which is ~22.99 g/mol. To convert mass to moles, you divide the given mass by the molar mass of sodium.
What is the mass of 1.2 x 10-3 moles of sodium chloride?
This mass is 69,6 mg.
How many moles of sodium oxide will be produced with 10 moles of sodium react with oxygen?
1 mole of Sodium Chloride weighs 58.5 grams (1 mole is the same as the molecular weight of a compound. The molecular mass of Sodium Chloride- NaCl is 23 [Na atomic mass] + 35.5 [Cl atomic mass] which is equal to 58.5 grams).Thus 10 moles would weigh 10x58.5 grams = 585 grams.The answer is 585 grams.
How many moles are in 4.5 x 10-3 g of sodium carbonate?
Dividing by the molar mass of sodium carbonate, we deduce that there are 4.25 x 10-5 moles in 4.5 x 10-3 grams of sodium carbonate.
How many grams are there in 10 moles of soduim?
The mass of 1 mole of a substance is the atomic weight of that substance. Na has an atomic weight of approx 22.99 g/mole → 10 moles weight 10 moles × 22.99 g/mole = 229.9 g
How many moles are present in 585 g of sodium chloride?
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.
How many atoms are present in 46.0 grams of sodium?
To determine the number of atoms in 46.0 grams of sodium, you first need to calculate the number of moles of sodium present. With the molar mass of sodium being 22.99 g/mol, you can divide the given mass by the molar mass to find the number of moles. Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms by multiplying the number of moles by Avogadro's number.
How many moles are in sodium carbonate?
To calculate the number of moles in sodium carbonate, you need to know the mass of the substance and its molar mass.
