Answer: There are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
1 mole of [tex]H_2O_2[/tex] molecule contains = [tex]6.023\times 10^{23}[/tex] molecules
Thus 7.9 mole of [tex]H_2O_2[/tex] molecule contains = [tex]\frac{6.023\times 10^{23}}{1}\times 7.9=47.6\times 10^{23}[/tex] molecules
Thus there are [tex]47.6\times 10^{23}[/tex] molecules in 7.9 mol of [tex]H_2O_2[/tex]
