I don't understand this I'm confused ​
skad [1K]

Explanation:

1.

Sodium, or Na, is 57.47% of the composition,

Hydrogen, or H, is 2.520% of the composition,

and Oxygen, or O, is 40.001% of the composition.

This is because mass% = mass/total mass x 100%.

2. For every 1 mole of C6H12O6, you need 6 moles of water. Multiply the 5.2 moles you are trying to make by the 6 moles of water you need, and you will need 31.2 moles.

3. x = 7.2 x 4 / 2 = 14.4 mol
