The volume of a gas sample is 22 L. at STP (Standard Temperature and Pressure). The density of the gas is 1.35 g/L. What is the mass of the gas sample, expressed to the correct number of significant figures?

h let me think

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

the temperature of the gas, in k, not celsius.
