Glucose (c6h12o6) has a single carbonyl group (-c=o) in its linear form. based on the number of oxygen atoms in glucose, how man
y hydroxyl groups (-oh) would you expect glucose to have?
1 answer:
Glucose is a hexose monosaccharide. It is one of the three major monosaccharides along with fructose and galactose. These are carbohydrates with a general formula of Cₓ(H₂O)ₓ, where x could be any number.
Now, you don't have to know the structural formula of the glucose to answer this. Just account all the elements in the glucose. You know that there are 6 oxygen atoms all in all. One of them belongs to the single carbonyl group. Consequently, that would mean that the remaining 5 oxygen atoms bond with hydrogen atoms to form 5 OH groups.
Just to be sure let us refer to the structural formula of glucose shown in the picture. It indeed has 5 OH groups.

Answer:
Approximately , assuming that this gas is an ideal gas.
Explanation:
Look up the standard room temperature and pressure: and
.
The question states that the volume of this gas is .
Convert the unit of all three measures to standard units:
.
.
.
Look up the ideal gas constant in the corresponding units: .
Let denote the number of moles of this gas in that
. By the ideal gas law, if this gas is an ideal gas, then the following equation would hold:
.
Rearrange this equation and solve for :
.
In other words, there is approximately of this gas in that
.
