how man molecules are there in 450 grams of Na2SO4.
the simple formula to determine of mole is NO OF MOL= GIVEN MASS IN gm/MOL:MASS OF COMP: , AND IMOL = 6.02X1023 . SO, 19. 077X1023 molecules are present in 450 grams of Na2SO4.

How many moles are in Na2SO4?
just one. If you were given a mass of Na2SO4, then you could find the number of moles by dividing the mass by the molar mass(total of the mass of all elements from the mass on the periodic table). But Na2SO4 by itself is just one mole.
How many grams of Na2SO4 are required to make 350 ml of 0.5M?
Molar mass Na2SO4 = 142 g/mole0.5 M = 0.5 moles/L = 0.5 moles x 142 g/mole = 71 g/L 350 ml = 0.350 L, therefore 71 g/L x 0.35 L = 24.85 g If using proper significant figures, it would be 20 g
How many grams of hydrochloric acid are needed to make a solution of 2 molar?
HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.
