How many atoms are in .190g of P2O5?
jasenka [17]
To go from grams to atoms, you first have to convert to moles and them to atoms. To do that, divide the amount in grams by the atomic weight (141.95 in this case) and then multiply by avagadros number (6.022×10^23). After you do all of this, you should get 8.06×10^20.

You've just solved a problem and the answer is the mass of an electron, me=9.11×10−31kilograms. How would you enter this number
mihalych1998 [28]

The mass of an electron can be expressed in the box as \boxed{{m_e} = 9.1 \times {{10}^{ - 31}}{\text{ kg}}}.

Further explanation:

Atom is the smallest particle that can be present in any element. It is also known as the building unit of matter. Each atom has a central part that is known as the atomic nucleus. There are three subatomic particles that constitute the atom. These particles are protons, neutrons, and electrons. The atomic nucleus consists of protons and neutrons, both are collectively called nucleons. Electrons revolve around the nucleus of an atom in definite orbits.

Protons are positively charged subatomic particles, electrons are negatively charged and neutrons have no charge. Since electrons carry a unit negative charge, these create an electric field around them. These also participate in nuclear reactions. The mass of an electron \left( {{m_e}} \right) is 9.1 \times {10^{ - 31}}{\text{ kg}}, that of protons is 1.6726219 \times {10^{ - 27}}{\text{ kg}} and that of neutrons is 1.674927471 \times {10^{ - 27}}{\text{ kg}}. The electrons are responsible for chemical properties of elements. The distribution and arrangement of electrons is used to predict whether the element will be inert or reactive.

Therefore the required answer is \boxed{{m_e} = 9.1 \times {{10}^{ - 31}}{\text{ kg}}}.
