Cm^3=1cm*1cm*1cm
=10mm*10mm*10mm
=1000 mm^3
Answer:
1 mole of water (H2O)
Explanation:
Water has a chemical formula of H2O, there will be 2 moles of hydrogen in every mole of water.
In one mole of water, there will exist approximately 6.02×10^23 water molecules.
So, there will be a total of 6.02×10^23×2≈1.2⋅10^24 hydrogen atoms.
