Answer» `3.67xx10^(26)` `6.6 xx 10^(23)` `3.67xx10^(24)` `6.0 xx10^(22)` Solution :Number of OXYGEN atoms in 34.2 G of sucrose `=(6.02xx10^(23)xx11xx34.2)/(342) = 6.62xx10^(23)` Number of oxygen atoms in 9 g of `H_2O` `=(6.02xx10^(23)xx90)/(18) =30.1xx10^(23)` Total number of oxygen atoms `(30.1 +6.62)10^(23)` `=36.72xx10^(23) = 3.672xx10^(24)`
