find the amount of moles using the formula for molarity: Molarity = moles/Liters of solution then multiply the number of moles by avogadros number
ps. convert to mM to M. 1 mM = 0.001 M
so calculate the mass C6H12O6? then divide that by 1.02?

no, you don't need the molar mass since you're not converting to grams
i'm just lost on the moles then how do i find that
with the molarity and the volume of solution given
molarity is a form of expressing concentration (in terms of moles per liter).. so basically by multiplying the molarity by the volume, you find the moles but you have to covert to molarity because mM meaning millimolar, 1 molar = 0.001 millimolar
so like \[\frac{ 2mL }{ 1mm} X \frac{ 1mm }{ 0.001 } ?\]
nope convert volume to liters .. 2mL = 0.002 L convert millimolarity to molarity 1.02 mM = 0.00102 M 0.00102 M x 0.002 L =
2.04X10^-6
looks right, i don't have a calculator around to check though
ok thank you so much
no problem
ps you still need to multiply by avogadros number
yea i figured that I'm trying to get a better number I would take that equations answer 2.04 ... and multiply it by avogadro's number right
yep, it's 2.04x10^-4 though don't forget
why 10^-4 i got -6
sorry -6 lol my mistake
haha its ok thank you again
lol no prob, good luck
