Complete equation, ionic equation, and net ionic equation for NH4C2H3O2(aq) + NH3 (aq)
The given blanks can be filled with meteorology, atmosphere, biosphere, SI, and scientific notation.
In the field of meteorology, scientists measure the pressure, temperature, and humidity. Their measurements come from the characteristics of the atmosphere, and hydrosphere, and they look at how the weather influences the biosphere and the geosphere. The units of their measurements come from SI and the metric system. The numbers usually are not large, so scientific notation is not used.
Density is defined as mass/volume (or m/v).
So,
(126.0 g)/(12.5 cm^3)= 10.08 g/cm^3
If your teacher requires correct significant figures, the answer is 10.1 g/cm^3.
If not, the first answer is fine.
