A student is attempting to make up 500.0 mL of a 0.278 M solution of FeCl3 from a stock solution which has a molarity of 2.6 M. How much of the stock solution (in mL) will they need to add to a 500.0 mL volumetric flask to make up the 0.278 M solution?

Scientists often have to deal with numbers that are either very large or very small. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each number in an alternate form.
