The compound is made of 2 oxygen molecules and the oxygen made of 20.61% its mass. If the molar mass of oxygen is 16, the molar mass of the compound will be:
2* oxygen* (16g/mol / oxygen) = 20.61% compound mass
compound mass= 32g/mol / 20.61%
compound mass= 155.26 g/mol
Answer:
Hydrogen has 0 neutrons.
Explanation:
You can find the # of neutrons by subtracting the Atomic Mass from the Atomic number. Hydrogen is a special case in which the atom has no neutrons.
It is false
