Question

Convert to decimal form: [1 each] a. 1.85 x 10' m b. 3.84 x 10* moles- c. 2.1683 x 10, mm. d. 5.80 x 101 g moles

Answer 1

a. When we multiply 1.85 with $10^5$ , we multiply with 100,000. We remove the decimal point from 1.85 and add three zeros.

b. When we multiply 3.84 with $10^{-4}$ we divide 3.84 with $10^{4}$ . We shift decimal point to left and add 3 zeros between decimal point and 3.

c. When we multiply 2.1683 with $10^{4}$ , we remove the decimal point.

d. When we multiply 5.80 with $10^{-1}$ , we divide 5.80 with 10. We shift decimal point to left.
