6.02 x 1023 atoms weigh out 63.55 grams copper.
No. of Molecules in water = 3.5mole x (6.02 x 10^23) molecules/mole = 2.107 x 10^24 molecules of H2O
Answer: 2, you divide the value by 1000, so... 2000/1000 = 2.
Initial temperature = -189.4 °C
<h3>Further explanation</h3>
Given
the volume of a gas is changed from 3.6 L to 15.5 L
final temperature = 87 °C = 87+ 273 = 360 K
Required
initial temperature
Solution
Charles's Law
<em>When the gas pressure is kept constant, the gas volume is proportional to the temperature </em>
The reactivity and other chemical properties of an organic molecule are primarily dependent upon <span>the attached functional group </span>of the molecule.
For example hydroxyl group (-OH) in alcohols or carboxyl group in c<span>arboxylic acid are poplar groups and that is why this compounds are polar.</span>
The atoms of functional groups are linked to each other and to the rest of the molecule with covalent bonds.
