Answer #1

The statement is True because we know molar mass of a substance =(mass of the substance in grams)/(amount of the substance is moles).

So it relates the number of moles to the number of grams of a substance and is a very useful quantity.

The statement is true because we know molar mass of a substance mass of the substance (in grams) amount of the substance Cin

    In Part A, you explored the relationship between molarity, the number of moles, and solution volume. However, when you prepare a solution, you are unable to directly measure the number of moles of solute. Instead, you can mass the solute and convert between the number of moles and mass using the molar mass of a substance as a conversion factor. The molar mass of a substance can be calculated based on its molecular formula; otherwise, it can be calculated from...
