A molecular biologist measures the mass of cofactor A in an average yeast cell. The mass is 96.15 pg . What is the total mass in
Morgarella [4.7K]

Given data:

Mass of cofactor A in an average yeast cell = 96.15 pg

Now:

1 picogram (pg) = 1*10^{-12} g

1 microgram (ug) = 1*10^{-6} g

Therefore, 1 pg = 1*10^{-6}ug

Mass of cofactor A in one yeast cell = 96.15 * 10^{-6} micro gram

Number of cells in the yeast colony = 105

Therefore, the total mass of cofactor A is given as:

Number of cells * mass of cofactor A per cell

= 105 cells * 96.15 *10^{-6} micro grams/cell = 1.009 * 10^{-2} micro grams
