A mole is a defined number of atoms/molecules of an element/compound. Therefore, the number of moles of NaCHO3 will depend on the mass of NaCHO3 that you have. To calculate the number of moles in a known sample, divide the mass of the sample (in grams) by the molecular weight.
The compound NaCHO3 contains sodium (Na), carbon (C), hydrogen (H), and oxygen (O) elements.
NaCHO3 is 27.367% Na
Usually written as, NaHCO3 Sodium bicarbonate
Of course 6 moles.
16 grams of oxygen how many moles is 0,5 moles.
moles of what?
55.8 moles
2 moles of Ca and 4 moles of OH
There are 4.5 moles of sodium fluoride in 4.5 moles of sodium fluoride.
this is a easy one. There are only 0.04166 moles.
The answer is 7,73 moles.
20 moles
