How many grams of Na3PO4 will be needed to produce 425 mL of a solution that has a concentration of Na plus ions of 0.900 M?
Let us find moles first. Molarity = moles of solute/Liters of solution ( 750 ml = 0.750 Liters ) 0.375 M Na2SO4 = moles Na2SO4/0.750 Liters = 0.28125 moles Na2SO4 =================== 0.28125 moles Na2SO4 (142.05 grams/1 mole Na2SO4) = 39.95 grams Na2SO4 needed ---------------------------------------you do significant figures!
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
What is the percentage by mass of phosphorus in Na3PO4?
(3)(30.97)/163.94*100=56.67%
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
What is the mass in grams of 4.5 moles of carbon?

2,196.10-12 pmol of Na3PO4. (p is pico)
What is the percentage by mass of phosphorus in Na3PO4?
(3)(30.97)/163.94*100=56.67%
In the formula for sodium phosphate Na3PO4 how many moles of sodium are represented?
the formula does not show how many moles are in a compound, but it tells how many atoms of an element that are in the compound...
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
