If the body fat has density of 0.94 g/ml and 3 quarts of fat are removed, how many pounds of the fat were removed from the patient?
How many grams of NaOH would you need to prepare 500mL of a 1M solution (assume 100% purity of the base)? M= (# of moles / L of solvent)
Aluminum oxide, Al2O3 (molar mass = 101.96), occurs in nature as a mineral called corundum which is noted for its hardness and resistance to attack by acids. Its density is 3.97 g/cm3. Calculate the number of atoms of aluminum in 15.00 cm3 of coru..
If 8.60 g of NaHCO3(s) are combined with 32.2 mL of 0.800 M H2SO4, how many moles of CO2(g) would be produced if reaction occurred as completely as possible. Calculate the number of moles of both reactants first and then identify limiting reactant..
a typical aspirin tablet contains 500. mg of c9h8o4. what amount moles of c9h8o4 molecules and what number of molecules
What is the molar solubility of AgCl in water. For AgCl, Ksp=1.8 x 10-10. Give your answer in moles per litre, accurate to two significant figures
suppose you wanted to dissolve 106 g of Na2CO3 in enough H2O to make 6.00L of solution what is the molar mass of Na2CO3.
Consider the acid HB with a Ka=5.8 x 10-10 (a) what is the kb for the B- ion and (b) what is the pkb
On titration of a sample weighing 0.573g , 94.1mL of 0.105 MNaOH was required to reach an equivalence point. Fumaric acid reacts with 1 mol ofHCl to give an addition product and with 1 mol of H2 to give a reduction product. ???what is the empirica..
What steps would you take to separate the following four organic compounds using an acid/base solvent extraction? Compounds: m-anisic acid, p-toluidine, thymol, indane
How about for a solution of nitric acid (which has pKa of -1.4) Do the calculation for a formal concentration. of 1M and for the formal concentration of 0.1M.
Draw every stereoisomer for 1,2-difluoro-1,2-dimethylcyclopentane. Use wedge-and-dash bonds for the substituent groups, and be sure that they are drawn on the outside of the ring,
Terminal alkynes are acidic compounds, with pKa values around 25. That means they are about: a. one million times more acidic than water b. one billion times more acidic than water c. one billion times less acidic than water d. one thousand times ..
