Answer:
17.1195 grams of nitric acid are produced.
Explanation:
Moles of nitrogen dioxide :
According to reaction 3 moles of nitrogen dioxides gives 2 moles of nitric acid.
Then 0.5434 moles of nitrogen dioxides will give:
of nitric acid.
Mass of 0.3623 moles of nitric acid :
Theoretical yield = 22.8260 g
Experimental yield = ?
Experimental yield of nitric acid = 17.1195 g
Answer:
Molality = 1.13 m
Explanation:
Molality is defined as the moles of the solute present in 1 kilogram of the solvent.
Given that:
Mass of 
= 26.5 g
Molar mass of = 32.04 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of water = 735 g = 0.735 kg ( 1 g = 0.001 kg )
So, molality is:
<u>Molality = 1.13 m</u>
<span>Tychonic System is a model of the Solar system that embraces all the benefits of Copernican and Ptolemaic systems, forming the most accurate one. This system was introduced by Tycho Brahe in16th century, and it looks like this: the Earth is placed at the center of the universe, the Sun, Moon and the stars revolve around the Earth, and the other planets, in their turn, revolve around the Sun. </span>
