if 1.2 g of sodium metal is reacted with 2 mL of H20, how many grams of NaOH will be produced

Answer 1

2Na+2H2O-->2NaOH+H2

2 mL H2O*(1g H2O/1 mL H2O)=2 g water

Since this is more grams than the sodium, and there is a one to one ratio, the sodium is limiting.

1.2g Na*(1 mol Na/22.99 g Na)*(2 mol NaOH/2 mol Na)*(40 g NaOH/1 mol NaOH)

2.1 g NaOH
