Answer:
There are 36 grams in 4.00 moles of Carbon.
Explanation:
In order to convert from moles of a substance into grams of the same substance, we need to use the substance's molar mass.
That means that in this case we use the<em> molar mass of Carbon</em>:
- 4.00 mol * 12 g/mol = 36 g
Thus, there are 36 grams in 4.00 moles of Carbon.
Answer:
lightning candel is not a physical change.
when you light the candel the wax gets melted which cannot be reversed.
as physical change is that change in which no new substances are formed abd is reversible.
In the option above shattering the plate doesnot make any chemical change likewise cutting hair also doesnot mean so, and boiling water can be condensed.

Google says it is 9.01218, idk if that helps
Mass of AlCl₃ : 93.39 g
<h3>Further explanation</h3>
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
So to find the number of moles can be expressed as
n = V x M
the volume of the solution = 330 cm³=0.33 dm³
the concentration of the solution = 283 g/dm³
mass of AlCl₃ :
