Answer:
3.47 × 10²³ C atoms
Solution:
Data Given:
Mass of Diamond = 48 mg = 0.048 g
M.Mass of Diamond = 12.01 g.mol⁻¹ (as it is purely Carbon)
Step 1: Calculate Moles of Diamond as,
Moles = Mass ÷ M.Mass
Putting values,
Moles = 0.048 g ÷ 12.01 g.mol⁻¹
Moles = 0.576 mol
Step 2: Calculate number of Carbon atoms,
As 1 mole of any substance contains 6.022 × 10²³ particles (Avogadro's Number) then the relation for Moles and Number of Carbon atoms can be written as,
Moles = Number of C Atoms ÷ 6.022 × 10²³ Atoms.mol⁻¹
Solving for Number of C atoms,
Number of C atoms = Moles × 6.022 × 10²³ Atoms.mol⁻¹
Putting value of moles,
Number of C atoms = 0.576 mol × 6.022 × 10²³ Atoms.mol⁻¹
Number of C atoms = 3.47 × 10²³ C atoms
Answer:
A has the highest concentration
Explanation:
I'll simply explain it this way;
get a color pour the whole color in a solution in container A then add a little drop in the another container(B).
you'll find out that the first container has a thicker color than container B the same thing goes for this, Beaker A has a thick looking color unlike the rest.
Answer:
the ozone molecules are constantly being made and destroyed by uv radiation, so yes
Explanation:
<em><u>pure substance:
</u>elements:<u />
they are made by one kind of atoms,, have their own properties cannot be broken down into simpler substances,,
<u>compounds:</u>
made by chemical reactions of elements joined together,,they have different properties has compared to the elements which make them in compounds elements may be separated by chemical means..
<u>impure substances :
</u>they are made by physical combinations,,and they may be separate by physical means ,,mixture is the example ,, also their properties do not change after becoming a mixture,,<u>
</u></em>
I do not see a question. Could you be more specific?
