Asample of a compound contains 32.0 g c and 8.0 g h. its molar mass is 30.0 g/mol. what is the compound’s molecular formula?

ch3
ch4
c2h4
c2h6

a sequence is a function whose domain is the set of natural numbers.

natural numbers are all the negative and positive integers

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
