Check out a sample textbook solutionStudents have asked these similar questions
To identify the substance, a chemist determined its density. By pouring a sample of the liquid into a graduated cylinder, she found that the volume was 35.1 mL. She also found that the sample weighed 30.5 g. What was the density of the liquid? What was the substance?
If a sample of gold alloy has a mass of 87.7 g and is 78.3% gold by mass, what percentage of the alloy is made up of other metals? Write your answer to the nearest tenth of a percent.
(I had to alter the wording of this question since it wasn't calculating significant figures properly, so if you got it wrong because of significant figures you can assume you probably actually got it correct.)
5) A student correctly determines that 17.1 grams of sucrose are needed to make 50 ml of a 1M
solution of sucrose. When making this solution in the lab, the student measured 50.0 ml of water in
a measuring cylinder and added that to a beaker. Then the student massed 17.1 grams of sucrose
and added it to that beaker. She then mixed the solution well and poured the resulting solution into
a graduated cylinder. To her utter shock, the volume of the solution was now 62.0 mL. Explain what
happened.
Describe the steps the student should have taken to prepare a 50.0 ml solution of
1M sucrose.
6) What volume of 0.10 M solution can be prepared using 11.6 g of NaCl?
