The average mass of a kernel of popcorn is 0.125 g. if 1 pound = 16 ounces, and 1 ounce = 28.3 g, then how many kernels of popcorn are there in 0.500 pounds of popcorn?

Average mass of a kernel of popcorn = 0.125 g

1 pound = 16 ounces, and 1 ounce = 28.3 g

how many kernels of popcorn are there in 0.500 pounds of popcorn = ?

0.500 pound = 16 x 0.500 ounces = 8 ounces

8 ounces = 8 x 28.3g = 226.4 g

Now divide this quantity by average mass;

226.4 / 0.125

= 811.2 kernels of popcorn
