Question

The concentration of each solution will be given in molarity (M). Molarity is a quantity that expresses the moles of solute present per liter of solution. A sodium hydroxide solution is labeled as 0.1020 M. 

i. Write that as a ratio of moles and liters. 

ii. If 11.25 mL of the 0.1020 M NaOH solution is used to titrate a solution, then how many moles of NaOH does that represent? 

iii. If the number of moles of unknown acid neutralized are determined to be 0.003443 mol unknown, what is the identity according to the associated mole ratio represented in 3)a. ?
