Answer:
Explanation:
Since no information was provided about the can of soda, let's take an example of 1 can of 12 fl oz (368 g) Coca-Cola.
The nutrition facts state that it contains 33 g of sugar. In order to calculate the number of molecules, we firstly need to know the molecular formula of sugar. Sugar can be represented by 
.
Our first step is to find the molar mass of sugar:
Secondly, dividing mass of sugar, 
, by the molar mass will yield the number of moles of sugar:
Finally, multiplying moles by the Avogadro's constant will yield the number of molecules:
Answer:
In glucose there are 6 carbon atom, atomic weight carbon is 12, so the molar mass is 72 and the percentage composition of carbon in C6H12O6=(72180)×100%=40% percentage by the mass.
During the winter solstices, we experience the longest day and the shortest night while during the summer solstices the sun is at its highest point in the sky.
<h3>What is the Solsticest?</h3>
The Solstices is the season that occurs at the moment the earth's tilt toward or from the sun is at a maximum. There are two seasons of Solstices which include the following:
- The winter solstices: This occurs when the sun is directly over the Tropic of Capricorn causing us to have the shortest day and longest night of the year.
- The summer solstices: The sun is at its highest elevations.
