Density Problems  Calculations with Grids Std4e
Assignment
1  Directions: Use Table C6 on p. 916 of your textbook to find densities
for the elements listed. Then rewrite
the DENSITY in the next column as shown in the examples. Last, solve the problems give in the far
right column on the back of this paper.
Number from 110 on the back of this paper, or a separate sheet of
paper, and show the grids for your
calculations and circle your answers.
Units of measure are essential.
See examples at the beginning of chart of this page.
Elements 
Density 

_____ g 
= 
_____ cm^{3} 
Number from 110 on the back of this paper. Show your calculations (with grids) by each number. 










Ex 
a. sulfur 
2.08 g/cm^{3} 

2.08 g S 
= 
1 cm^{3} S 
If you are given 13 cm^{3} of S, how much would it
weigh in grams? 

Ex 
b. calcium 
8.65 g/cm^{3} 

8.65 g Ca 
= 
1 cm^{3} Ca 
If you are given 41.7 g of Ca, how many cm^{3} of Ca would you have? 

1. cobalt 






If you are given 24 cm^{3} of Co, how much would
it weigh in grams? 

2. boron 






If you are given 105 g of B, how many cm^{3} of B
would you have? 

3. gallium 






If you are given 11 cm^{3} of Ga, how much would
it weigh in grams? 

4. iron 






If you are given 82.2 g of Fe, how many cm^{3} of
Fe would you have? 

5. mercury 





If you are given 13 cm^{3} of Hg, how much would
it weigh in grams? 

6. oxygen 






If you are given 91.9 g of O, how many cm^{3} of O
would you have? 

7. zinc 






If you are given 2.91 cm^{3} of Zn, how much would
it weigh in grams? 

8. silver 






If you are given 77.3 g of Ag, how many cm^{3} of
Ag would you have? 

9. tin 






If you are given 2.77 g of Sn, how many cm^{3} of
Sn would you have? 

10. tungsten 





If you are given 152 g of W, how many cm^{3} of W
would you have?

Solutions to
example problems in Assignment 1:
Ex – a (using grids, shown here as fractions)
13 cm^{3} of S 2.08 g of S
 x  = 27 g of S
1 1 cm^{3} of S
Ex – b (using grids, shown here as fractions)
41.7 g of Ca 1 cm^{3} of Ca
 x  = 4.82 cm^{3} of Ca
1 8.65 g of Ca
Assignment 2  Directions: Solve each
of these problems as you did in Assignment 1 above. Use the densities from Assignment 1. Show your work. If
you do not use grids, you will not get any points for this assignment
11. cobalt If you are given 214 g of Co, how many cm^{3} of Co would you have?
12. boron If you are
given 42.7 cm^{3} of B, how much would it weigh in grams?
13. gallium If you are given 64.9 g of B, how many cm^{3} of B would you have?
14. iron If you are
given 10.4 cm^{3} of Fe, how much would it weigh in grams?
15. mercury If you are given 175.9 g of Hg, how many cm^{3} of B would you have?
16. oxygen If you are
given 64,310 cm^{3} of O, how much would it weigh in grams?
17. zinc If you are given 20.78 g of Zn, how many cm^{3} of Zn would you have?
18. silver If you are
given 7.369 cm^{3} of Ag, how much would it weigh in grams?
19. tin If you
are given 0.3813 cm^{3} of Sn, how much would it weigh in grams?
