G) The mass of a beaker is 40.94 g. After 5.00 mL of concentrated hydrochloric acid solution is pipetted into the beaker, the combined mass of the beaker and hydrochloric acid is 46.92 g. From the data, calculate the density of hydrochloric acid solution. Show your solution.

2 answers

46.92 g = mass beaker + HCl
-40.94 g = mass beaker
------------------
....5.98 = mass HCl
density = mass/volume = ?
You know the mass and from the problem you know the volume. Solve for density.
Uhm so nobody knows its been a WHOLE YEAR and nobody have the answers oh my oh my
