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.
At STP 1 mole of gas occupies 22.414 liters. This volume is what is usually meant by the molar volume, although one can also speak of molar volumes of substances that are not gaseous at STP. Since at STP water occupies very nearly 1 cc per gram, and since 1 mole of water molecules weighs very nearly 18 grams, the molar volume of water is about 18 cc.
