Given that mH = 1.007825 u, is the mass of a hydrogen atom 1H greater than, less than, or equal to 1/12 the mass of a 12C atom?
Select the correct answer and explanation. Given that = 1.007825 , is the mass of a hydrogen atom greater than, less than, or equal to 1/12 the mass of a atom? Select the correct answer and explanation. 1/12 of the mass of a 12C atom is greater than 1 u. Therefore, the mass of the hydrogen atom is greater than 1/12 of the mass of a 12C atom. 1/12 of the mass of a 12C atom is less than 1 u. Therefore, the mass of the hydrogen atom is less than 1/12 of the mass of a 12C atom. 1/12 of the mass of a 12C atom is exactly 1 u. Therefore, the mass of the hydrogen atom is less than 1/12 of the mass of a 12C atom. 1/12 of the mass of a 12C atom is exactly 1 u. Therefore, the mass of the hydrogen atom is greater than 1/12 of the mass of a 12C atom. 1/12 of the mass of a 12C atom is exactly 1 u. Therefore, the mass of the hydrogen atom is equal to 1/12 of the mass of a 12C atom.
1/12 of the mass of a ¹²C atom is exactly 1u. Therefore, the mass of the hydrogen atom is greater than 1/12 of the mass of a ¹²C atom.
Explanation:
The unified atomic mass unit is defined as 1/12 of the mass of a ¹²C atom:
1u = 1/12 m ¹²C
Also, the unified atomic mass unit is equal to the mass (in grams) of one mole of a substance, so knowing that 1 mol is equal to 6.022x10²³ atoms, the unified atomic mass unit measured in grams is:
Starting from this definition, we can calculate the mass of ¹H atom respect to the mass of a ¹²C atom:
Therefore, the mass of a ¹H atom is greater than 1/12 the mass of a ¹²C atom.
Isn't a hypothesis making a theory? Based on that I guess the answer would be A. Making a theory, because you making the hypothesis is not part of testing it.
