Question

A molecular biologist measures the mass of cofactor A in an average yeast cell. The mass is 96.02

 pg. What is the total mass in micrograms of cofactor A in a yeast colony containing 10^5

 cells? Write your answer as a decimal.

Answer 1

Use dimensional analysis.

10⁵ cells x 96.02 pg/cell = 96.02x10⁵ pg = 9.602x10⁶ pg

Converting this to micrograms, we have ....

9.602x10⁶ pg x 10^-6 ug/pg =9.602 ug
