How many molecules are in 2.50 moles of H2O?
0 1.51 X 1024 molecules of H20
0 4.15 X 10-24 molecules of H20
0 3.01 X 1024 molecules of H20
O 8.31 X 10-24 molecules of H20

[tex]We\ are\ given:\\No.\ of\ moles\ of\ H_2O\ provided=2.5\ moles\\Now,\\We\ know\ that,\\ Avagadro's\ Constant=6.022*10^{23}\\Now,\\We\ also\ know\ that:[/tex]

[tex]No.\ of\ particles=No.\ of\ moles*Avagadro's\ Constant\\Hence,\ here,\\No.\ of\ molecules\ in\ 2.5\ moles\ of\ H_2O=2.5*6.022*10^{23}\\Hence,\\No.\ of\ molecules\ in\ 2.5\ moles\ of\ H_2O=15.055*10^{23}\ H_2O\ molecules\\Now,\\No.\ of\ molecules\ in\ 2.5\ moles\ of\ H_2O=1.5055*10^{24}\ H_2O\ molecules\\ or\ 1.51*10^{24}\ H_2O\ molecules[/tex]
