When I do these problems, the answer that I received does not seem correct when I go back to check the answer within the equation. Am I possibly entering the scientific notations into my calculator wrong?

Part B: Using scientific notation in calculations and interconverting between scientific
notation and standard notation
Scientific notation is used to make very large and very small numbers more convenient to work
with. When working with dilute acid and base solutions, the concentrations of the H3O* ion and
OH are related by this equation at 25 C:
[H301[OH] = 1.0 X 1014
Note: entering scientific notation in to your calculator is different for different calculators. Take
