A student titrates a 5.26mL sample of a solution of KOH with unknown molarity. The titration requires 3.82mL of a 4.21M HF solution. What is the molarity of the KOH solution?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

i just learnt this recently but i need to look through my notes again

i would say b

explanation:

but i think i would need more information than that
