How many grams nh3 are equivalent to 9.3 x 1023 molecules nh3?

To solve this, we need the Avogadros number to convert to moles then multiply with molar mass to convert to mass in grams.

moles = 9.3 x 10^23 molecules * (1 mol / 6.022 x 10^23 molecules)

moles = 1.54 moles

Molar mass of NH3 is 17 g/mol:

mass = 1.54 moles * 17 g/mol

mass = 26.25 g

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
