How is the mass of carbon related to the mole?

1 answer:

4 0

Answer:

Simply put, you can go from moles to grams and vice versa by using the mass of 1 mole of that substance, i.e its molar mass. For example, the molar mass of carbon is 12.011 g/mol. This means that 1 mole of carbon, or 6.022⋅1023 atoms of carbon, weigh 12.011 g.

Give the formulas for all of the elements that exist as diatomic molecules under normal conditions. See if you can do this witho

GenaCL600 [577]

Answer:

They are:

H2, N2, O2, F2, Cl2, Br2, and I2.

Note: whether the element At molecule is monoatomic or diatomic is incredibly arguable. While some say it exists as diatomic because it is a halogen like bromine, iodine etc, At is in fact extremely unstable and no one has ever really studied the molecules on it, so, when others say it is monoatomic, this is also based on calculations. But the other 7 elements listen above is for sure diatomic.
