What is heliums mass number?
Most helium has a mass number of 4. The rare 3He isotope has a mass number of 3. The mass number is the integer total of protons and neutrons for a given isotope. For example radioactive carbon-14 has a mass number of 14, while carbon-12 (the most common stable form) has a mass number of 12.
What is the number of protons of helium?
Helium is number 2 on the Periodic Table, and the number of its mass is 4. So, therefore it has 2 protons, 2 neutrons, and 2 electrons !
What is the mass of 2.50 mol of Helium?
Helium molecule is mono atomic. 1 mole = 6.023 x 1023 atoms of helium So, 2.5 moles = 2.5 x 6.023 x 1023 atoms of helium or 15.058 x 1023 atoms of helium
