Answer = 0. 43 moles.

Explanation

1. Use the equation 9.8 grams * 1 mol/22.99 grams to find out how many moles you can make.

2. Use a calculator and insert 9.8 * (1)/(22.99), which should give you 0.426272292301.

3. Since 9.8 has 2 significant figures, round 0.426272292301 to 2 significant figures, which would be 0. 43 moles.
