How many milliliters of a stock solution of 2.00 m kno3 would you need to prepare 100ml of 1.50 m kno3?

To solve this we use the equation, 

M1V1 = M2V2

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

2 M x V1 = 1.50 M x 100 mL

V1 = 75 mL of the 2 M KNO3 solution

let that person have a turn to speak : )

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
