Ahydrocarbon contains 85.7% carbon and the remainder
ishydroge. its molar mass is 70g/mol. determine the empirical
andmolecular formulas of the compound.
2nabh4(s) + i2(s)-> b2h6(g) + 2nai(s) + h2 (g)
suppose you use 1.203g nabh4 and excess iodine, and youisolate
0.295g b2h6. what is the percent yield of b2h6?
