Answer:
Some formulas for calculating mole are
Mole = Mass/ Molar mass
Mole = no of particles / avogadros constant
NB : no of particles can be no of atoms , no of ions , or no of molecules 2. Avogadros number or constant = 6.02 times 10 ^23
so we will be using the second formula
Mole = no of particles / avogadros constant
Mole = 5.03 x 10 ^23/6.02 x10^23
Mole = 8.355x10^45
hope it helps :)
Explanation:
in order for a scientific theory to become a scientific law it needs to be tested with generations of data to confirm that it is really true.
Answer:
the mass number of the atom or ion is 6
Since there are 63.01284 grams to one mole of HNO3, then 12.5 moles would be in 450 grams of it.
