How many moles of HNO3 are present in 31.0mL of a 1.80M solution of nitric acid?


use formula:
m = (moles of solute)/(liters of solution)

question 1:
1.80 = (moles of solute)/(0.031)
moles of solute = 0.0558

question 2:
1.10 = (0.110)/(l of solution)
= 0.1 l of solution
= 100 ml of solution


formula works moles of solute , liters of solution. if given grams or ml, make sure convert.

how many milliliters of 1.10m koh solution needed provide 0.110 mol of koh?

if explain answer that'd great. i'm confused.
