Answer:
A
Explanation:
Isotopes are atoms of the same element with the same number of protons and electrons but different numbers of neutrons.
Isotopes can also be defined as atoms of the same element with the same atomic number but different mass numbers e.g isotopes of chlorine, oxygen and so on.Oxygen for instance has three isotopes with the same atomic number,8 and different mass numbers,16,17 and 18.
Mass to mass: moles A x(mole ratio of B/A) and mass to mole: extract the data from the question
The Molarity will increase.
Answer:
The answer is argon. Pls mark as brainliest
All you have to do is multiply the amount of moles by 6.02x10^23 which is Avagadro's number.
