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 do you convert 40 mmol of Sodium to grams?
A mole is 6.022*10^23 of a substance. An element's atomic mass, the number below the element's atomic symbol on the periodic table, is the number of grams one mole of that substance weighs. Multiply the number of moles of substance (here, 40 if you meant 40 moles or .04 if you meant millimoles) by the atomic mass of the substance (here, sodium's is 22.98977) to get the final answer in grams.
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
How do you calculate the mass in grams of 425 sodium atoms?
To calculate the mass of an atom, 1amu = 1.66*10^-24 and sodium has a mass of 22.99amu. Therefore, 425 sodium atom would be 425*(22.99*(1.66*10^-24))=1.6219445~-20. With the sig fig, the final answer is: 1.62*10^-20g
How many atoms does sodium have if it has 23.0 g?
Number of particles (atoms) =Avogadro's number (parts per mole) * [ mass (grams) / molar mass (grams per mole) ]So: N = 6.02*10+23 * 23.0 / 22.99 = 6.02*10+23atoms sodium
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 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 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 grams of NaCl are present in 10.00 moles?
10 moles of sodium chloride have 584,397 g.
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
What is the mass of 1.2 x 10-3 moles of sodium chloride?
This mass is 69,6 mg.
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 moles in 43 grams of sodium sulphate?
6.066 into 10(up 23 )
How do you convert 40 mmol of Sodium to grams?

What is meant by the mass mass percent concentration of a solution?
This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.
