A solution is prepared by dissolving 15.0 grams of cesium chloride (CsCl) in 125.0 grams water. What is the mass percent of cesium chloride in this solution

The correct answer is "atomic weight".

3-isopentane; 3-methylbutane, and 1,2-methylpropane do not meet iupac rules, so they are wrong names.the only valid name onthe list is 2-methylbutane, which is the same isopentane.this is its formula:                   ch2                    |ch3 - ch - ch2 - ch3answer: 2-methylbutane

Its not chemical its not radiation and its not convection because there is not movement of fluids so it is thermal conduction
