How many moles of NaOH are present in 26.5 mL of 0.100M NaOH?

Question

How many moles of NaOH are present in 26.5 mL of 0.100M NaOH?



moles:

Answer 1

0.100 M NaOH means 0.100 moles NaOH/Liter of solution

Since we have 26.5 ml of solution, we convert that to liters, and multiply...

26.5 ml x 1 L/1000 ml x 0.100 moles NaOH/L = 0.00265 moles NaOH (to 3 significant figures)

Answer 2

moles / liter = molarity

convert ml to l by taking 26.5 ml/ 1000ml = 0.0265 l

now to convert to moles simply take molarity and mutiply by liter = moles

0.100 M * 0.0265 l = 0.00265 moles round it = 0.00300 moles NaOH

Answer 3

0,100 M NaOH means 0,1 mol of NaOH is in 1 L or 1000 mL of solution,

but we are given 26.5 mL solution of NaOH

so, (26,5 mL x 0,100 mol) : 1000mL= 0.003 mol NaOH
