4 and 2 electrons are present.
Answer:
To calculate molarity, divide the number of moles of solute by the volume of the solution in liters. If you don't know the number of moles of solute but you know the mass, start by finding the molar mass of the solute, which is equal to all of the molar masses of each element in the solution added together.
Explanation:
try starting with 35.0 and dived it by the volume
12cm cubed.
Formula is length x width x height and in this case it would be 2x3x2 which equals 23
By using the quantum model of the atom and John Dalton's model you can predict that the methane molecule will most likely be made up of Hydrogen and Carbon.
