1,5 moles of potassium carbonate have 276,41 g.
No. of moles=wt. of substance/molecular wt. hence, wt. of substance= 2.38*100=238
2,8 moles of calcium carbonate have 240,208 g.
The answer is: 2,96 moles.
The answer is 0,274 moles.
250 grams CaCO3 (1 mole CaCO3/100.09 grams) = 2.50 moles of calcium carbonate
No. of moles=wt. of substance/molecular wt. hence, wt. of substance= 2.38*100=238
2,8 moles of calcium carbonate have 240,208 g.
234 grams :)
# of moles = grams of substance / molar mass of substance molar mass of Barium =137.33 grams/mole #moles of Barium = 22.3 grams/ 137.33 grams/mole = 0.162382582 moles
The answer is: 2,96 moles.
The answer is 0,274 moles.
You find the number of atoms from the number of grams of a given substance by:Find the Moles of the Substance by multiplying the grams of the substance by the molar mass of the substance. ( Molar mass equals mass of substance per 1 mole of substance.)Grams x Molar Mass of Substance = Moles of SubstanceTake the moles of the substance and multiply it by Avogadro's Number (the number of atoms in 1 mole of substance, or simply 6.022x1023).Moles of Substance x Avogadro's Number (6.022x1023) = atoms of Substance
250 grams CaCO3 (1 mole CaCO3/100.09 grams) = 2.50 moles of calcium carbonate
0,028 moles carbonic are obtained.
To calculate the number of moles from grams, you must divide by the substance's molar mass
The molar mass of sodium hydrogen carbonate is 84 grams per mole, therefore 0.5 moles of it weighs 42 grams.
