The short answer to your question is that each bacterium must weigh 5.96 x 10^-5 grams.
The way to get this is by using a formula for exponential growth. The formula is
y = a(1+r)^x
In this formula, y is your ending quantity. A is your beginning quantity. R is the rate of increase. X is the number of times that increase occurs.
R is usually expressed as a decimal, so in this case it is 1 because the rate of increase is 100%.
So your equation will be
y = 1(1+1)^24 or y = 2^24 which is equal to 16,777,216.
To get the weight of each bactermium, divide 1000 grams by the number of bacteria.
