You are given 10.0 mL of a 0.893 M solution of glucose. However, it was accidentally left uncovered on a sunny windowsill over the weekend. When you return the following Monday, you find that the water has evaporated away, leaving the glucose behind. What is the mass of the glucose in the container?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.
