Question

A molecular biologist measures the mass of Cofactor A in an average yeast cell. The mass is 77.91pg. What is the total mass in micrograms of Cofactor A in an average yeast colony containing 10^5 cells? Write your answer as a decimal.

Answer 1

The total mass of Cofactor A in a yeast colony containing 10⁵ cells is 7.791 micrograms, calculated by multiplying the mass per cell by the number of cells and converting picograms to micrograms.

Step-by-step explanation:

To calculate the total mass in micrograms of Cofactor A in an average yeast colony containing 10⁵ cells when the mass of Cofactor A in an average yeast cell is 77.91pg, you will need to multiply the mass of Cofactor A per cell by the number of cells in the colony. Because there are 10⁵ cells in the colony, the total mass in picograms would be:

77.91 pg/cell × 10⁵ cells = 7,791,000 pg

To convert this value into micrograms (since there are 1,000,000 picograms in a microgram), you would divide by 1,000,000:

7,791,000 pg / 1,000,000 pg/μg = 7.791 μg

Therefore, the total mass of Cofactor A in the yeast colony is 7.791 micrograms.

Answer 2

In this question, you are given the average cofactor mass per cell (77.91pg) and the total cells count(10^5 cells). You are asked how much cofactor that will be found from those cells(microgram= 10^6 picogram). Then the calculation would be:
Cofactor mass= cofactor per cell * cell count= 77.91pg/cell * 10^5 cells= 7.791 x 10^6pg

Then convert the picogram(pg) into microgram: 7.791x 10^6pg/ (10^6pg/microgram)= 7.791 microgram
