Ahhh just figured it out. I forgot we made a 10^-1 dilution of the original culture.

So its 7,500 cells per mm^3
Multiply that by 1000 to convert it into ml = 7.5x10^6
and Multiply that by 10 to make it equal to the original dilution so 7.5x10^7ml

Hmmm, i'm still stuck with the ^-1

ahhh damn sorry to hear bro. I guess the money was too good for him to pass up. What are you looking to get into?

If you did a 10^-1 dilution you need to multiply by .1 not by 10.

software startups. I would have left too. He was one of the only professors they had teaching physical chemistry which is ranked as the most difficult one year course out of the entire undergrad curriculum. It was as tough on him as it was on us.

why .1?
10^-1 is 10% strength of original. So multiplying by 10 will bring it back to its original strength.

As a side note...Is the rest of the CORe keeping up with this?

Good deal. It's tough to get anywhere in science w/o a phd anymore, and the money is usually garbage to boot.

isn't microbiology fun??

I fucking hate it...but sadly its a compulsory module in Aquatic Zoology. Oh well, module ends at the end of Jan.

i'm getting confused here hold on let me go back to the original question.

is the 7500 per cubic mm with or without the dilution?

Keeping in mind that one cubic cm = 1ml you can convert from cubic mm to mL very easily.

Number of yeast cells is 7500mm^3 with the dilution at 10^-1

Cheers for your help with this mate

ohh ok then you are looking for the number of cells in the original sample without the dilution? Yeah you're right you multiply by 10.

Cool.
So i've worked that out I THINK as 7.5x10^7ml (I think) and its asking for ml^-1....im confused.

This was all overseen by my professor, and he said my result was right...but I just dont know how he got there or if he made a slight mistake.
