1 answers

Sanket .........✨ 4 years, 1 month ago

The main difference between molar mass and molecular mass is that the mass of a mole of a substance is measured in molar mass, whereas the mass of a molecule of the substance is measured in molecular mass. Molar mass is the total mass of 6.022 x 1023 molecules (Avogadro number) of a substance.

Prachi Pal 4 years, 1 month ago

In an atom, electrons (negatively charged) revolve around the positively charged nucleus in a definite circular path called orbits or shells. Each orbit or shell has fixed energy and these circular orbits are known as orbital shells. The energy levels are represented by an integer (n=1, 2, 3…) known as the quantum number. This range of quantum numbers starts from the nucleus to the side with n=1 having the lowest energy level. The orbits n=1, 2, 3, 4… are assigned as K, L, M, N…. Shells and when an electron attains the lowest energy level it is said to be in the ground state. The electrons in an atom move from a lower energy level to a higher energy level by gaining the required energy and an electron moves from a higher energy level to a lower energy level by losing energy.

Chandana Gupta 4 years, 1 month ago

As we know n=w/m & n=N/N⁰(N⁰=Avogadro No.=6.022×10²³) So, w/m=N/N⁰ w=given weight=23g m=molecular mass(here, for Na)=23g N=no. of particles=? So, 23/23=N/6.022×10²³ 1=N/6.022×10²³ 6.022×10²³=N So, the answer is 6.022×10²³ molecules.
