The mass of a beaker is 5.333 g. After 5.00 mL of a concentated hydrochloric acid solution is pipet Ted into the beaker, the combined mass of the beaker and the hydrochloric acid sample is 11.229 g. From the data, what is the measured density of the hydrochloric acid solution?
Do the following multiplication and division calculations. Give a final answer with the correct number of significant figures and the correct units. Units can cancel or multiply just like number factors.
(2.5 x 103 m/s) x (5.00 x 10-6 s) = ?
