Question

Multiply or divide the following measurements. Be sure each answer you enter contains the correct number of significant digits. 7.808 * 1.3 ml. = Is x 5 ? 840.8 g + 0.52 ml. = | 713.2 mol + 38.8 L

Answer 1

Part 1

(7.808 g/mL) x (1.3 mL) = 10.1504 g

In multiplication lower number of significant figures are to be considered for the final answer

= 1.0 * 10^1 g

Part 2

(840.8 g) / (0.52 mL) = 1616.92 g/mL

In division lower number of significant figures are to be considered for the final answer

= 1.6 * 10^3 g/mL

Part 3

(713.2 mol) / (38.8L) = 18.38 mol/L

In division lower number of significant figures are to be considered for the final answer

= 1.84 * 10^1 g/mL
