C) Condensation is the opposite of evaporation.


Condensation is the phase when water droplet form. Ex) When you have a glass of ice water the water droplets on the outside of the glass are condensation.

Evaporation is when a liquid heats up and turns into a steam or mist. Ex) When you boil water the steam that comes up from the pot is actually water!!

Therefore condensation is caused by cold temperatures, and evaporation is caused by hot temperatures.

The molar mass of gallium (Ga) is 69.72 g/mol.
Thepotemich [5.8K]

Answer:

2.35 x 10²⁰ atoms Ga

Explanation:

After converting from mg to g, use the molar mass as the unit converter to convert to moles. Then using Avogadro's number, 6.022 x 10²³ convert from moles to atoms of Ga.

27.2mgGa*\frac{1g}{1000mg} *\frac{1 mol Ga}{69.72gGa} *\frac{6.022*10^2^3 atoms Ga}{1 molGa} = 2.349 * 10^2^0 atoms Ga

Then round to 3 significant figures = 2.35 x 10²⁰ atoms Ga.
