Answer:
1.42 M
Explanation:
First calculate the amount of moles.
that's done by dividing the mass with the molecular mass so 660g / 310.18 g/mol = 2.13 mol
Then you can calculate the molarity by dividing the moles with the volume so 2.13 mol / 1.5 l = 1.42 M
(without rounding: 1.418531175 M)
Compounds that primarily contain carbon are known as organic compounds.
Molecules will move faster and spread apart on warmer temperatures The colder it get the slower the molecules move so naturally those water molecules are on the path to freezing
Using simply rational here:
1 Water= two hydrogen atoms+ 1 oxygen atom
The numbers provided would create seven water molecules based on having fourteen hydrogen’s (which would be seven times the two required for water) and seven oxygen.
So, 7
