Answer:
37.3g
Explanation:
Formula of the compound:
FeCl₃
Number of chloride ions = 4.13 x 10²³ ions
First find the number of moles in this ions;
6.02 x 10²³ ions are contained in 1 mole of a substance
4.13 x 10²³ ions contains = 0.69mole chloride ions
Now;
3 mole of chloride ions are contained in 1 mole of FeCl₃
0.69 mole of chloride ions will contain = 0.23mole of FeCl₃
To find the mass;
Mass of FeCl₃ = number of moles x molar mass
molar mass of FeCl₃ = 55.8 + 3(35.5) = 162.3g/mol
Mass of FeCl₃ = 0.23 x 162.3 = 37.3g

3.When you have a plant in your house you breathe better
Explanation:
i dont have an answer for the second one tho
Answer:
Explanation:
Given that,
Mass, m = 10 g
Volume, V = 24 cm³
We need to find the density of the substance. We know that, the density of a substance is given by :
Density = mass/volume
So,
So, the density of the substance is .
