2.17 x 10²³molecules
Explanation:
Given parameters:
Number of moles of water = 0.36moles
Unknown:
Number of molecules in a water sample = ?
Solution:
A mole of substance is the amount of substance that contains the Avogadro's number of particles which is 6.02 x 10²³ particles.
The particles are molecules, formula units, number of protons, neutrons, electrons, e.t.c;
Since 1 mole of any substance = 6.02 x 10²³ molecules
0.36 moles of water = 0.36 x 6.02 x 10²³ = 2.17 x 10²³molecules

Explanation:
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
53.3% + 6.7% = 60%, 100% - 60% = 40%. 40% of glucose is made of carbon. Since there are only three types of atoms in glucose, and the amount of hydrogen and oxygen is already given, this means that whatever percentage is left (40%) has to be carbon.
Answer:
Explanation:
Examples of pure substances include tin, sulfur, diamond, water, pure sugar (sucrose), table salt (sodium chloride) and baking soda (sodium bicarbonate). Crystals, in general, are pure substances. Tin, sulfur, and diamond are examples of pure substances that are chemical elements.
