Question

8. 3.42 g of sucrose are dissolved in 18 g of water in a beaker. The numbers of oxygen atoms in the
solution are:
(a) 6.68 1023
(b) 6.09 x1022
(c) 6.022 1023
(d) 6.022 x1021
​

Answer 1

Answer:

The number of oxygen atoms in the solution are. or 342g = 1 mole of sucrose. 3.42 g = 0.01 mole of sucrose. ∴ 0.01 mole of sucrose will contain O-atoms.
