Question

4.
(a) Define and explain mole and Avogadro's number with examples.
(b) Given the equation. CH4(g) + 2O2(g) → CO2(g) + 2H2O(g) + Heat​

Answer 1

Answer:

a. Avogadro's number is an absolute number: there are 6.022×1023 elementary entities in 1 mole. ... The mass of one mole of a substance is equal to that substance's molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.
