QuestionEvaluate (1.28×105)+(1.13×103)(1.28 \times 10^{5}) + (1.13 \times 10^{3}) in scientific notation. Then, (7.26×106)−(1.3×104)(7.26 \times 10^{6}) - (1.3 \times 10^{4}). Lastly, find the mass of 480,000,000480,000,000 bacteria if one bacterium has a mass of 2×10−122 \times 10^{-12} gram.

Studdy Solution
Rewrite the result in scientific notation.
Total mass=9.6×10− gramTotal\, mass =9.6 \times10^{-}\, gramSo, the mass of the population of bacteria after30 hours is 9.6×10−9.6 \times10^{-} gram.
