Lina20 [59]

primarily ionic include = sodium iodide( NaI) , calcium chloride ( CaCl2)

primarily covalent include - Ammonia (NH3) , Methane ( CH4) and

Glucose (C6H12O6)

Explanation

ionic bond is formed when there is complete transfer of electron between atoms. It occur between metal which donate electrons and a non metal which accept electrons.

for example in formation of CaCl2, ca donate 2 electron to 2 Cl atom, while 2 Cl atom accept the 2 electrons to form ionic bond.

Covalent bond is formed when two or more non metal form bond by sharing electrons pairs.

For example in NH3 3 pairs of electron are shared. to form covalent bond.

Answer:

16.92 g C13H18O2

Explanation:

If the molecular mass of C13H18O2 is 206.3 amu, then molar mass of C13H18O2 is 206. 3 g/mol.

So, if we have 0.082 mol C13H18O2, than it is

206.3 g/mol*0.082 mol = 16.92 g C13H18O2.
