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!
So the answer is: density= 1.1792g ?
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.
Can you show me the numbers I need to punch in? I am totally confused?
Sure! To find the density of the hydrochloric acid solution, you can follow these steps:
Step 1: Calculate the mass of the hydrochloric acid sample.
- Subtract the mass of the empty beaker from the combined mass of the beaker and hydrochloric acid sample:
Mass of hydrochloric acid sample = Combined mass - Mass of empty beaker
= 11.229 g - 5.333 g
= 5.896 g
Step 2: Calculate the volume of the hydrochloric acid sample.
- The volume of the hydrochloric acid sample is given as 5.00 mL.
Step 3: Use the formula for density to calculate the density of the hydrochloric acid solution.
- Density (ρ) = Mass (m) / Volume (V)
- Substitute the values we found:
Density = 5.896 g / 5.00 mL
Step 4: Convert the units, if necessary.
- The density is currently in grams per milliliter (g/mL). If you need the answer in a different unit, you can convert it using appropriate conversion factors.
That's it! Now all you need to do is carry out the calculation in Step 3 to obtain the measured density of the hydrochloric acid solution.
mass of acid = 11.299-5.333 grams
density = mass/volume
= (11.299 - 5.333) g / 5 mL
