A student prepares a solution by dissolving 78.2 g of substance B in 0.336 kg of benzene (C6H6). Substance B does not form ions in solution (remains intact) and has a molecular mass of 96.3g/mol. What is the freezing point depression of the solution (incrementT) if benzene has a kf

the solar system used to have much dust particles option no d

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
