An experiment requires 42.5 g of sulfuric acid, which is easier to measure by volume than by mass. What volume in mL should be measured out, if the density of the sulfuric acid is 1.84 g/cm^3?
What is the ionization state of aniline (protonated, deprotonated, or a mix) at pH 1, 4.6, and 14?
Does that indicate the original alcohol is in that mixture? What is the source of 2-bromopentane?
A solution containing Pt4+ is electrolyzed with a current of 4.20 A. How long will it take to plate out 65% of the platinum in 0.50 L of a 0.010 M solution of Pt4+
How many moles of carbon, hydrogen, & oxygen are present in a 100g sample of ascorbic acid? Ascorbic acid (vitamin C) contains 40.92% carbon, 4.58% hydrogen, and 54.50% oxygen by mass. Assume a 100 g sample of ascorbic acid.
