Not much.
Ice is only water, when the molecules are submitted to low temeperatures and have formed a crystalline arrangement of low density. In ice, the molecules arange themselves in hexagons with hydrogen bonds binfing each molecule.
When ice melts it turnes into water and the molecules leave the crystalline shape and come back to their normal density. In water, not all molecules are binded forming short and irregular lines.
→ In the image below, you can see the arrangement of ice and water.

Answer:
There are 0.0267 moles of oxygen in 0.658 grams of magnesium nitrate.
Explanation:
Mass of magnesium nitrate = m = 0.658 g
Molar mass of magnesium nitrate = M = 148 g/mol
Moles of magnesium nitrate = n
1 mole of magnesium nitrate has 6 moles of oxygen atoms. Then 0.004446 moles magnesium nitrate will have :
There are 0.0267 moles of oxygen in 0.658 grams of magnesium nitrate.
0.008 ÷ 51.3 = 0.0002
