Find out how much the donuts cost then divide that by $10,000 and you will get your answer
Oxygen is the 8th element in the periodic table. This means that oxygen has 8 protons<span> and 8 electrons. In order to get the number of neutrons you take the atomic weight in this case 15.9999~16 and you subtract it by the number of protons (16-8) (o_O)

Molarity and normality are the ways of expressing concentration which includes the volume of the solution.
As we know,
Molarity is defined as the number of moles of solute dissolved in 1L of the solution. Thus,
M = no. of moles of solution/ Volume of solution on litres.
while, Normality is the number of gram equivalents of the solute dissolved per litre of the solution.
N = Gram equivalent of the solute/ volume of solution in litres.
while, the other concentration expressing terms such as mole fraction, molality includes the mass of the solution and solvent respectively.
