PLEASE ANSWER SELECTIONS A AND B WITH ENCODED SOLUTIONS. THANK YOU!
Transcribed Image Text:Direction: Read and answer the following problems using the factor-label
method or dimensional analysis. Please Show Your Work (PSYW).
Example : At 25 °C a metal registers a density of 1.8 g/ cm³. Calculate its
density in kg/m³?
Solution
x (100 cm)³ =
(1 m)3
1.8 g x 1 kg x 1 000 000 cm³ = 1800 kg/ m3
cm3
1.8 g x 1kg
cm3
1000 g
1000 g
1 m³
1800 kg/ m³ or 1.8 x 103 kg/ m3
