Mg: 2
O : 6
Explanation:
You can quickly find out the number of valence electrons by looking at where the element is on the periodic table and referring to the table that is attached.
It contains one mol of carbon atoms. For the better calculating in the chemical reaction, we often use the mol as unit to describe the amount. Carbon is consists of carbon atoms. And the mol number is related to the mass of atoms. The molar mass of carbon is 12 g/mol. So the answer is 1 mol carbon atoms.
The new pressure of the gas would be 505.58 torr
<h3>Boyle's law</h3>
According to Boyle's law, the pressure of a gas is inversely proportional to its volume, provided that the temperature is constant.
This can be mathematically represented as: P1V1 = P2V2
In this case, P1 = 759.4 torr, P2 is what we are looking for, V1 = 97.6 mL, and V2 = 146.6 mL
Hence, P2 = P1V1/V2 = 759.4x97.6/146.6 = 505.58 torr
