Answer :
Final answer:
To calculate the mass of 1 cubic centimeter of sand, multiply the mass of one grain (7 x 10^-4 grams) by the number of grains in 1 cc (1,000), which equals 0.7 grams or 7 x 10^-1 grams in scientific notation.
Explanation:
The average mass of one grain of sand is 7 x 10-4 grams. To find out the mass of 1 cubic centimeter of sand, we multiply the mass of one grain by the number of grains in 1 cubic centimeter:
Mass of 1 grain of sand = 7 x 10-4 grams
Number of grains in 1 cc = 1,000 grains
Mass of 1 cc of sand = 7 x 10-4 grams/grain x 1,000 grains/cc
Mass of 1 cc of sand = 0.7 grams or 7 x 10-1 grams in scientific notation.
