Answer:
The density of Ammonia : 6.25.10⁻⁴ g/cm³
Further explanation
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}ρ = Vm
ρ = density
m = mass
v = volume
A common example is the water density of 1 gr/cm³
Ammonia has a density of 0.625 g/L, then convert to g/cm³ :
\begin{gathered}\rm 1~L=1~dm^3=10^3~cm^3\\\\0.625~\dfrac{g}{L}\times \dfrac{1~L}{10^3~cm^3}\\\\\rho=\dfrac{0.625}{10^3}}\dfrac{g}{cm^3}=\boxed{6.25.10^{-4}\dfrac{g}{cm^3}}\end{gathered}

Answer:
5.30x10²³g
Explanation:
A mole can be understood as an amount of something.
One mole of eggs are 6.022x10²³ eggs
One mole of atoms are 6.022x10²³ atoms
One mole of molecules are 6.022x10²³ molecules
And 1 mole of M&M are 6.022x10²³ M&M. As 1 M&M weighs 0.88g, 1 mole will weigh:
0.88g*6.022x10²³ =
<h3>5.30x10²³g</h3>
