## Question:

The density of ammonia gas under certain conditions 0.795 g/L. Calculate its density in g/cm^3.

......g/cm^3

## Dimensional analysis:

Dimensional analysis is a technique to convert a measurement from one of its units to another. One unit of measurement can be multiplied by a series of fractions that are essentially the same measurement, just in different units. For example:

{eq}1\ m = 100\ cm {/eq}

By multiplying the fraction:

{eq}\large \frac{100\ cm}{1\ m} {/eq}

to one meter, one can obtain:

{eq}$$1\ m$$ {/eq}{eq}\large $$(\frac{100\ cm}{1\ m})$$ {/eq}

Here, the {eq}1\ m {/eq} quantity can be cancelled out. This will then leave only the measurement in terms of the particular converted quantity in the equation.

Given:

• {eq}\displaystyle \rho =0.795\ g/L {/eq}

To determine the density in the specified units, we can use dimensional analysis. That is, for one...
