Answer:
3.25×10²⁴ molecules.
Explanation:
From the question given above, the following data were obtained:
Number of mole of CO₂ = 5.4 moles
Number of molecules of CO₂ =?
The number of molecules of CO₂ in 5.4 moles can be obtained as follow:
From Avogadro's hypothesis,
1 mole of CO₂ = 6.02×10²³ molecules
Therefore,
5.4 moles of CO₂ = 5.4 × 6.02×10²³
5.4 moles of CO₂ = 3.25×10²⁴ molecules
Thus, 5.4 moles of CO₂ contains 3.25×10²⁴ molecules.
B. The atomic number. This is because the atomic number is the same as the number of protons an element has, and the number of protons defines an element.
Answer:
Because it contains only two elements.
Explanation:
A binary compound is a compound made up of only two elements. Barium chloride contains:
1. Barium.
