Question

How many milliliters of a stock solution of 5.00 M KNO3 would you need to prepare 250 mL of 0.250 M KNO3?

Answer 1

so the equation you need here is M1v1=M2v2

Answer 2

yes thats right @peter14

Answer 3

so then what would i do next?

Answer 4

you know the initial molarity, the final molarity, and the final volume

Answer 5

plug it into the equation

Answer 6

do you get the answer @selenamalter ?

Answer 7

no, im a little confused still

Answer 8

Substitute. Do you know what the letters in the formula stand for?

Answer 9

it same with peter's formula
M1 v1 = M2 V2
5 v1 = 0.25 x 250
get it?

Answer 10

okay, let me see here

Answer 11

1.25?
