If you take 1.5cm3 of the above suspension and dilute it to a final volume of 12cm3: a) how many cells cm-3 are there in the diluted solution ? b) how many cells are there in the diluted solution ?

Answer 1

?????????????? "final volume" ???????????????? . . . num sells=6*150,000=900,000 . . . ????????? yu want the sell density if take 1.5 cc & thin it?????? mi ges at wot yu tri tu sae is the original density be 150,000 sells per cc . . . xpand 1.5 tu 12=8 tu 1, so nu density=(1/8) old density . . . =150,000/8=18,750 . . .
