A solution containing 17.0 g of a molecular compound dissolved in 100.0 g of water has a boiling point of 101.5 °C. Calculate the molar mass of the compound. The b for water is 0.512 °C/m.

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o
