Answer:
Explanation:
We usually approximate the density of water to about at room temperature. In terms of the precise density of water, this is not the case, however, as density is temperature-dependent.
The density of water decreases with an increase in temperature after the peak point of its density. The same trend might be spotted if the temperature of water is decreased from the peak point.
This peak point at which the density of water has the greatest value is usually approximated to about . For your information, I'm attaching the graph illustrating the function of the density of water against temperature where you could clearly indicate the maximum point.
To a higher precision, the density of water has a maximum value at , and the density at this point is exactly
.
Answer: The mass percent of hydrogen in ascorbic acid is 4.5 %
Explanation:
In , there are 6 carbon atoms, 8 hydrogen atoms and 6 oxygen atoms.
To calculate the mass percent of element in a given compound, we use the formula:
Mass of hydrogen =
Molar Mass of ascorbic acid =
Putting values in above equation, we get:
Hence, the mass percent of of hydrogen in ascorbic acid is 4.5 %.
