To calculate the number of moles we will use Avogadro's number, which relates the number of molecules contained in a mole of any substance, the relationship between moles and molecules is as follows:
In the statement we are given the molecules with 3 significant figures, therefore the answer must also have 3 significant figures. So the answer will be: In 5.25x10^29molecules are 8.72x10^5 mol of sucrose
The answer is A.
We know the formula for molarity :
<u>Molarity = Number of moles ÷ Volume</u>
<u />
Let's assume there are 0.6 moles of NaCl in 1 liter of ocean water.
Then, mass of salt is :
- Mass of one mole salt × 0.6
- 58.5 × 0.6
- 35 grams
