Hey there!
A mole is measured in atoms, molecules, particles. It's kind of a loose sort of measurement, just unit of the substance.
Since there is a ratio of 1 to 1 nitrogen to oxygen, there will be the same amount of molecules as atoms of nitrogen.
2.25 moles of NO gas are formed from 2.25 moles of nitrogen.
Hope this helps!
Well basically, light is released when an excited electron returns to a lower energy state. Visible Light is part of the electromagnetic spectrum, and is a kind of radiation emitted.
Answer:
2x10⁻⁴cm and 7.9x10⁻⁵ inches
Explanation:
Micrometer, μm, is an unit of length. Could be related with another units of lenght as, for example:
1.0μm = 1x10⁻⁴cm
1.0μm = 3.93701x10⁻⁵ inches
That means, 2.0μm are:
2.0μm * (1x10⁻⁴cm / 1μm) = 2x10⁻⁴cm
And:
2.0μm * (3.93701x10⁻⁵ inches / 1μm) = 7.9x10⁻⁵ inches
Explanation:
because the energy it can't be calculated
Molecular weight of HBr = 80.91 g/mol.
We know that, 1 mole of HBr = 80.91 g/mol
Therefore, 2 mole of HBr = 80.91 x 2
= 161.82 g.
Hence, 161.82 g of HBr should be dissolved in 1 liter solution, to obtain 2 M solution.
