Asked by Amy

The mass of a beaker is 5.333g. After 5.00 mL of a concentrated hydrochloric acid solution is pipetted 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 solution?

Can you please show me a step by step way to answer this. I have many other questions similar to this and a sample of how to complete this answer would help me solve the others.

Thank you!

mass of acid = 11.299-5.333 grams

density = mass/volume

= (11.299 - 5.333) g / 5 mL

I think you must be overthinking this problem.

11.229 g = mass HCl + empty beaker
-5.333 g = mass empty beaker
--------------------
?? = mass HCl

Then density HCl = mass HCl/volume HCl. The mass is given in the problem.

So the answer is: density= 1.1792g ?

No. You must have punched a wrong key somewhere.

Can you show me the numbers I need to punch in? I am totally confused?
