Some of the common problems that affect the big toe joint include: Bunions. Bunions are an enlargement of the big toe joint and can cause pain from shoe pressure or from damage occurring within the joint. Our goal when treating bunions is to eliminate pain and stop or slow the growth of the bunion.
We know that volume occupied by one mole of a gas is its molar volume. This applies to a liquid and a solid too. So, molar volume of water, a liquid is the volume occupied by one mole of water, in any form. So, 1 mole of water occupies 18 grams. Since density of water is almost equal to 1, we take the grams of water as volume of water. So, Molar volume, or the volume occupied by one mole of water would be 18 milliliters.
One drop of water has the volume of about 0.05 mL. Because the density of water is 1, the mass is 0.05 g. The molar mass of water (H2O) is 18.0 grams/mol (1.008 + 1.008 + 16.0). This means there is one mole of water in 18.0 grams. One mole is 6.02 Ã 1023 molecules. Then you can convert grams to number of atoms:
