Without doing any calculations, determine which mass is closest to the atomic mass of carbon. without doing any calculations, determine which mass is closest to the atomic mass of carbon. 12.00 amu 12.50 amu 13.00 amu

The mass closest to the mass of carbon is 12.00 amu

This is because carbon is used as a standard compound in chemistry, and its mass is defined as being 12.00 amu per mole of carbon. Its definition as a standard is such that the mole is defined as, "the amount of substance containing the same number of atoms as 12 grams of carbon-12".

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)
