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

51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.
<h3>How to find the Number of moles ?</h3>
To calculate the number of moles use the formula
Number of moles =
=
= 1.9 mol
4NH₃ + 5O₂ → 4NO + 6H₂O
4 mol of NH₃ react with oxygen to given 6 mole of water.
So 1.9 mol of NH₃ produces =
= 2.85 mol of water
Mass of water = Molar Mass of water × Number of moles of water
= 18 × 2.85
= 51.3 gram
Thus from the above conclusion we can say that 51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.

Hi there!
I think populations' safety living near nuclear power plants are compromised. If there were a leak, the poison would have a greater potential to kill people living close to the source than farther away.
I think people should be taught and obtain an escape procedure in the event of a nuclear leak emergency. When a leak near them occurs, it is more likely that they can escape faster.
Hope this helps!
Answer:
75.2 degree Fahrenheit was the predicted high temperature.
Explanation:
Predicted high temperature in the Spain = T' = 24°C
In Spain temperatures are measured in Celsius. But we have to calculate the temperature in Fahrenheit .
To convert this temperature into Fahrenheit, we use the conversion factor:
75.2 degree Fahrenheit was the predicted high temperature.
