Density Calculations – Refer to the table on page 312 of your textbook
To get full marks for each question:
1. Answer all questions on loose-leaf. SHOW ALL OF YOUR WORK!
2. Write out the formula for what you need to find (e.g. m= DxV)
3. Write in the units for each value (e.g. m= 3.2g/mL x 0.25mL = 0.8g)
4. Write a sentence for each answer using the table on page 312.
(e.g. The mass is 0.8g. The substance is Jell-O).
5. Indicate whether or not the substance is a solid or a fluid (e.g. The substance is a
fluid).
6. Failure to follow these steps will results in lost marks.
