A solution of fructose, C6H12O6, a sugar found in many fruits, is made by dissolving 42.0 g of fructose in 1.00 kg of water. What is the molal concentration of fructose the solution

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Naoh + hbr -> nabr (salt) + h2o ca (oh)2 + 2hbr - - - > ca (br)2 + 2h2o

Ithink the answer is b.
