3. Compound A is provided as a 500mM solution. If 12.5 mL is taken and added to 12.5mL of water, how many moles (or millimoles / micromoles) are there per 0.1mL of the diluted solution?

Answer 1

It's 500 mM to start. You dilute it 12.5 to 25 which makes it now 250 mM or 0.250 moles/L. So how many moles are in 0.1 mL?

Answer 2

I don't know what is it

Answer 3

Answer 4

moles = M x L
moles = 0.250 x 0.0001 L = ?
