Methyl chloromethyl ether is an organic compound with the formula CH3-O-CH2Cl. This liquid is a very good solvent and it has a density of 1.0605 g/cm3at 20 ºC and a molar mass of 80.52. g. a) What is the mass in grams of 8.2 x 1011molecules of this compound? b) What is the mass in grams of the oxygen present in 6.47 cm3of this liquid. c) How many hydrogen atoms are there in 2.3 x 1019molecules of methyl chloromethyl ether? d) How many molecules of methyl chloromethyl ether are there in 13 drops of this solvent?

i would say b

explanation:

but i think i would need more information than that

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
