Thus problem is providing us with the mass of iron (III) oxide as 12.4 g so the moles are required and found to be 0.0776 mol after the calculations:
<h3>Mole-mass relationships:</h3>
In chemistry, we use mole-mass relationships in order to calculate grams from moles and vice versa. In this case, since we are given the mass of iron (III) oxide as 12.4 g one can calculate the moles by firstly quantifying its molar mass:
Then, we prepare a conversion factor in order to cancel out the grams and thus, get moles:

I think the answer is False.
The correct answer is a suspension.
A suspension is a mixture containing relatively large particles that settle fast
A homogenous mixture is a mixture where everything looks the same throughout and is all in the same phases
A colloid is a heterogenous mixture where the particles are small enough to stay suspended (usually talking about gaseous solutions)
And a solution is a homogenous mixture where the particles are too small to even reflect light
Answer:
According to research, the concentration of gold ions in the seawater is 10⁻¹⁴g/cm³.
