80 mL of water are added to 20 mL of a 1.5 M (concetration) of potassium bromide. What is the final molarity?
I did M1 x V1 = M2 x V2 but the answer I got is 0.375M ...its supposed to be 0.30 M /:

You did everything fine you jus forgot sig figs = significant figures. always look at your given measures 80ml ,20ml and 1.5 and find the lowest number of sig figs which all of them are two so your answers should have two sig figs in them which will round your 0.375 to 0.30 M :)
