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 of calcium are in 425 g calcium (Ca)?
425 g calcium (Ca) is equal to 10,604 moles.
How many moles of calcium are in 425 g?
To calculate the number of moles of calcium in 425 g, you need to divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. moles = 425 g / 40.08 g/mol ≈ 10.61 moles of calcium.
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
