Take 5.25 grams and give it proportionally to the carbon
0.9226 * 5.25 grams = 4.84 grams Carbon
Find the number of moles
(4.84 grams carbon)/(12.01 grams/mol) = 0.403 moles Carbon
The number of atoms in a mole of a substance is called Avogadro's number.
There are 6.022 * 10^23 atoms in one mole of anything
(0.403 moles Carbon) * (6.022 * 10^23 atoms/mole) = 2.43 * 10^23 atoms of Carbon
The number located in the top right corner of the ion is +2
An ion is an atom or group of atoms which possess an electric charge.
The charge on an ion can be obtained by using the following formula:
<h3>Charge = Proton – Electron </h3>
With the above formula, we can obtain the charge of the ion given in the question above as illustrated below:
Proton = 16
Neutron = 17
Electron = 14
<h3>Charge =? </h3>
Charge = Proton – Electron
Charge = 16 – 14
<h3>Charge = +2</h3>
Therefore, the charge on the ion is +2

Monitoring and regulating nuclear waste generated and issues associated to it the US.
To solve this we use the
equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.
2.5 M x V1 = 1.0 M x .250 L
<span>V1 = 0.10 L or 100 mL of the 2.5 M HCl solution is needed
Hope this helps.</span>
Alpha, beta and gamma radiation are all types of radiation that can be emitted from the nucleus of an atom. Apart from this they are different. Alpha radiation consists of a helium nucleus, beta radiation consists of an electron (or positron) and gamma radiation consists of very high energy electromagnetic radiation.
