Question

3.42 gm of sucrose are dissolved in 18 g of water in a beaker. calculate the no. of oxygen atoms in the solution?

Answer 1

Explanation:

3.42 g = 0.01 mole of sucrose. ∴ 0.01 mole of sucrose will contain O-atoms. Step 2: 18 g of water (H2O) = 1mole of water. 1 mole of water (H2O) contains O-atoms =6.022×1023 atoms.
