| September 23, 2021 | education
Given:
m (H2) = 2g
N-?
Solution:
n (nu) = mass of substance / mol. weight
M (H2) = 1 * 2 = 2 g / mol
n (H2) = 2/2 * 1 = 1 mol.
N (number of molecules) = n * N a
N a is Avogadro’s number = 6.04 * 10 ^ 23 1 / mol is the number of molecules in 1 mole of a substance.
N = 1 * 6.04 * 10 ^ 23 1 / mol = 6.04 * 10 ^ 23 1 / mol
Answer: 6.04 * 10 ^ 23 1 / mol
