Density and Unit Conversions

Practice flashcards covering density formulas, the triangle method for algebraic rearrangement, and specific unit conversion examples from the lecture notes.

What is the basic formula for density as stated in the notes?

$$Density = \frac{mass}{volume}$$

What are the symbols and units shown for the components of the density formula?

Mass is represented by $(kg)$ and Volume is represented by $(m^3)$, resulting in Density symbols of $kg/cm^3$ or $kg/m^3$.

According to the Triangle Method, how is mass ($m$) calculated?

$$m = D \times V$$

According to the Triangle Method, how is volume ($V$) calculated?

$$V = \frac{m}{D}$$

Based on the given values $m = 301\,g$ and $v = 15.6\,cm^3$, what is the calculated density?

$$D = 19,294.87\,kg/m^3$$

What calculation is used to convert $19.29\,g/cm^3$ to $kg/m^3$?

$$19.29\,g/cm^3 \times \frac{1\,kg}{1000\,g} \times \frac{(100\,cm)^3}{(1\,m)^3} = 19,294.83\,kg/m^3$$
