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.
Could you convert .10 mol of NaNO3 to grams?
#moles = mass/molar mass mass = #moles*molar mass mass = .10 moles*(atomic weight of na+atomic weight of N+3(atomic weight of oxygen)
How many grams of NaCl are present in 10.00 moles?
10 moles of sodium chloride have 584,397 g.
How many moles are there in 180gm of water?
10 moles of water (molar mass 18.0 g/mol) in 180 g, because 180 /18.0 = 10
What is the atomic mass of helium if you know that 2.5 mo of helium has a mass of 10 grams?
Atomic mass = weight in gram / moles = 10 / 2.5 = 4 amu
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
What is the mass of 1.2 x 10-3 moles of sodium chloride?
This mass is 69,6 mg.
10 moles sodium have the mass of what grams?
1 mole Na = 22.989770g 10 moles Na = 10 x 22.989770g = 229.89770g
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 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.
What conversion factor for sodium is used to change mass to moles is?
2.54 times 10 to the 23 power
How many moles are in 10 grams in sodium phosphate?
The formula mass of sodium triphosphate, Na3PO4 is 3(23.0)+31.0+4(16.0)=164.0 Amount of sodium triphosphate = 10/164.0 = 0.0610mol
How many moles of sodium atoms correspond to 1.56x1021 atoms of sodium?
1.56 X 10^21 atoms of sodium ( 1 mole Na/6.022 X 10^23) = 0.00259 moles sodium or 2.59 X 10^-3 moles sodium
What would 124 sodium atoms weigh?
Sodium has an atomic mass of 29.990 g/mol. This means that 124 sodium atoms have a mass of 3718.76 amu, if the isotopes follow the average. To find in grams, the following must be used: 124 sodium atoms equal 2.0598 * 10-22 moles, so 124 sodium atoms have a mass of 6.177 *10-21 grams.
How many moles of sodium oxide will be produced when 10 moles of sodium react with oxygen This is the formula for the reaction?
Balanced equation. 4Na + O2 -> 2Na2O 10 moles Na (2 moles Na2O/4 moles Na) = 5.0 moles Na2O produced
How many moles are present in 585 g of sodium chloride?
There are 10 moles present in 585 g of sodium chloride.
What can make 20 moles of sodium chloride?
20 moles of elemental sodium and 10 moles of elemental chlorine, which contains two atoms per molecule.
