You have two solutions of sodium chloride. One is a 2.00 M solution, the other is a 4.00 M solution. You have much more of the 4.00 M solution as well as you mix the solutions together. Which of the subsequent could be the concentration of the final solution?
Given that aprotic solvents are not practical for unimolecular processes (little if any reaction occurs via a unimolecular pathway) draw the skeletal structure of the major organic substitution product when (2S,6R)-2,6-dibromo-6-methyloctane is tr..
Combustion analysis of a 13.42 g sample of equilin which contains only carbon, hydrogen, and oxygen produced 39.61 g CO2 and 9.01 g H2O. The molar mass of equilin is 268.34 g/mol. Find the molecular formula for equilin.
How many moles of N2 molecules are present in a 0.151 L sample of dry air at 0.0356 atm and 23.8 °C ? (The mole fraction of N2 = moles of N2 / total moles of dry air = 0.7809.)
