Calculation of molar concentration
« on: November 07, 2020, 12:42:34 PM »
Can anyone help me to solve the problem?
Calculate the molar concentration of 8.45 ± 0.04 mL ammonia solution with a density of 0.2517 ± 0.0046 g/mL which was diluted to 0.5000 ± 0.0002L

You could compare the density with tables of density vs. concentration, e.g. https://wissen.science-and-fun.de/chemistry/chemistry/density-tables/density-of-ammonia/. Unfortunately, no aqueous ammonia solution has a density of 0.2517 g/mL, so there must be a mistake in the question. (Should that be an ammonia concentration of 0.2517 g/mL?)
