What is the mass of a 4He nucleus?

In summary, a "noob" in chemistry is someone who is new to the field and lacks experience. Common mistakes made by noobs include improper measurement and mixing of chemicals, not following safety protocols, and misinterpreting results. To improve as a noob in chemistry, one should study the basics, practice experiments, and seek guidance. Essential tools and equipment for a noob include safety gear, beakers, test tubes, and a Bunsen burner. While it is possible to conduct experiments at home, it is important to do so safely and with supervision, following proper procedures and starting with simple experiments.

NOT A HOME WORK PROBLEM

what does the following means.

4He

and it says that a He nucleus has mass of 6.4*10-27 Kg

how would i calculate the mass of 4He

do i take mass of 4He to be 6.4*10-27 Kg?

help, haven't done chemistry after getting out of school..i only do physic..in uni

thanks in advance

4He means Helium-4, the Helium isotope with atomic number 4 (two protons, two neutrons). As opposed to Helium-3 (two protons, one neutron) for instance.
