No of moles of Carbon, C = mass/ molar mass.
Molar mass of carbon = 12.0107. We only have to calculate the no of moles
of carbon to obtain carbon's mass. .
From Sucrose chemical formula C12H22O11 we know that there are 12
carbon atoms.
So there are 1.4x10^(20) x12 = 16.8 x 10^20 carbon atoms.
We will use avogardo's number to find out the number of carbon molecules
in the compound.
From Avogadro's no. One mole of any substance equals to 6.022140857
atoms.
So X mole contains 16.8 * 10^(20) carbon atom
(16.8x10^20 carbon atoms)/6.022 x10^23 particles/mol = 0.00279 mols
The molar mass of carbon is 12.0107g/mol so we'll multiply to get the mass:
0.00279 mols x 12 = 0.03348.

GOOD MORNING DIDI be happy
Answer:
The answer to your question is:
Explanation:
Ion is an atom that carries out a positive or a negative charge.
It is formed when an atom loses electrons. Yes, when an atom loses electrons then is formed a positive ion.
It is usually a nonmetallic element. Incorrect. Ions can be form by metallic or non metallic ions.
It has more electrons than protons. Yes, when an atom gains electrons is formed a negative ion.
It is formed when an atom gains protons. I think is incorrect, ions are formed when they gain or lose electrons not protons.
