how many moles are in 2.00 g salicylic acid?, what is mass of 5.00ml acetic anhydride if the density is 1.08g/ml?,how many moles of acetic anhydride are in this mass?, starting with 2.00g of salicylic acid, assuming acetic anhydride is in excess, what is the theoretical yield of asprin in grams.
How many copies of a protein need to be present in a cell in order for it to be visible as a band on an SDS gel? Assume that you can load 100 μg of cell extract onto a gel and that you can detect 10 ng in a single band in the gel. The concentration of protein in cells is about 200 mg/mL, and a typical mammalian cell has a volume of about 1000 μm3 and a typical bacterium a volume of about 1 μm3. Given these parameters, calculate the number of copies of a 120-kd protein that would need to be present in a mammalian cell and in a bacterium in order to give a detectable band on a gel. You might try an order-of-magnitude guess before you make the calculations.
How many milliliters of O2 gas at 25 ∘C and 1.00 atm pressure are obtained by the thermal decomposition of 0.240 g of KMnO4? The balanced equation for the reaction is 2KMnO4(s)→K2MnO4(s)+MnO2(s)+O2(g).
answer in ml
How many milliliters of O2 are consumed in the complete combustion of a sample of hexane, C6H14, if the reaction produces 789. mL of CO2? Assume all gas volumes are measured at the same temperature and pressure. The reaction is 2C6H14(g) + 19O2(g) 12CO2(g) + 14 H2O(g)

How many lemons batteries would it take to start a car?
Note: All numbers must be entered as 5000 or 5e3 or 5.0e3 and not with commas as in “5,000” and not as fractions as in “3/4” and not as percentages as in “70%”.
Please explain/break down these problems for me so that I can practice on other similar problems.
