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.
A mole is defined as the amount of a substance whose mass in grams equals the atomic, molecular, or formula-unit mass in atomic mass units. Example 1: Water (H2O) has two hydrogen atoms and one oxygen atom per molecule. The two hydrogen atoms each have an atomic mass of 1.008, the oxygen atom has an atomic mass of 15.999, the sum for all three atoms is 18.015. So a mole of water molecules has a mass of 18.015 g. Example 2: Beryllium has an aromuc mass of 9.01. So a mole of beryllium atoms has a mass of 9.01 g.
