First, you need to be given the gram formula mass of this molecular or related conditions that can calculate this. Then you need the empirical formula and calculate the gram formula mass of empirical formula. Then use them to get the ratio. Finally you can get the molecular formula.
Answer:
When atoms have fewer than eight electrons, they have an inclination to react and type a lot of stable compounds.
Thus, associate atom continues to create bonds till associate octet of electrons is formed. this can be called octet rule by Lewis.
Answer:
An ionic bond
Explanation:
An M⁺ cation will be attracted to an X⁻ anion.
The bond formed by a cation-anion attraction is an ionic bond.
<h3>Answer:</h3>
Mass = 96.47 g
<h3>
Solution:</h3>
Data Given:
M.Mass = 28.97 g.mol⁻¹
Moles = 3.33 mol
Mass = ??
Formula Used:
Moles = Mass ÷ M.Mass
Solving for Mass,
Mass = Moles × M.Mass
Putting values,
Mass = 3.33 mol × 28.97 g.mol⁻¹
Mass = 96.4701 g
Rounding to four significant numbers,
Mass = 96.47 g
The three broad classes of elements are:
Metals
Metalloids
Nonmetals
