Calculate the number of oxygen atoms in 2.00 moles of [tex]$Mn_2O_7$[/tex].
Answer (2)
first you should know that there is seven oxygen atoms in one Mn2O7 So 2.00 moles of Mn2O7 contain 14.00 moles of oxygen... Then you multiply this no. with Avagadro no.... from formula Number of moles= no. of particles/avagadro's no.. 14.00×6.02×10²³=84.28 atoms of oxygen...
In 2.00 moles of M n 2 O 7 , there are 14.00 moles of oxygen atoms, which amounts to approximately 8.41 × 1 0 24 oxygen atoms. To find this, we calculated the oxygen atoms per molecule first, then converted moles to atoms using Avogadro's number. This highlights the relationship between moles and the quantity of atoms present in a substance.
