Carbon is the reference taken to assign the atomic mass unit
- One twelfth of the mass of unbound carbon-12 is taken as 1amu
- The unit for the atomic mass constant is Dalton (Da)
- This unit is standard when doing calculations in chemistry and physics
- 1amu = 1.6605x10⁻¹⁹g
- This was also derived from the law of definite proportions
- This standard has been set by the International Union of Pure and Applied Chemistry (IUPAC)
- The IUPAC is responsible for assigning various standards such as the nomenclature of various compounds, and updating the periodic table of elements.
- According to the IUPAC carbon is the reference taken to assign the atomic mass unit

Most <span>scientists </span>suggest diminishing carbon dioxide outflows. Less carbon dioxide in the climate would be relied upon to diminish the quantity of biotic calculates biological systems. A biotic element is any living part that influences the number of inhabitants in another living being, or the earth. This incorporates creatures that expend the life form and the living nourishment that the living being devours.
Answer:
490.83 oK
Explanation:
First of all, we better agree on the meaning of the word <em>adiabatically</em>. It means without the loss or gain of heat. So nothing is given up to or taken from the environment.
This also assumes that no change has occurred in the pressure.
T1 = 310 oK
T2 = ?
V1 = 12 L
V2 = 19 L
T1/V1 = T2/V2
310 / 12 = x/19 Multiply both sides by 19
310*19 / 12 = T2 Multiply 310 * 19 on the left.
5890 / 12 = T2 Divide by 12
490.83 = T2
