    Ok guys, this one is phucking killing me,

    A person has a brain that weighed 1.20 kg and contained 1.35x10^10 cells. Assuming that each cell is completely filled with water (density of water= 1.00g/ml), calculate the length of one side of such a cell if it were a cube.

    In cm:

    If the cells were spread out into a single layer that was a single cell thick, what would the surface area be in square meters?





    I need help figuring out the problem, I don't want just the answer, if anyone can help it would fucking rock!!!!

    Whooo!!!! UPDATE!!!!

    So I'm now in college chem and its kicking my ass! haha everything that we covered in a year of high school chem has been covered in a month. Im back to trying to figure out limiting reactants and percent yield. Exam is tomorrow at 8pm CST. Studying all day and tomorrow. Was curious to see if anyone had a good way of finding the limiting reactant and percent composition of elements in chemical formulas. Thanks in advance for any help! Ready to be done with Chemistry!
