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.
Solution. Calculate the number of moles of solute present. Moles of NaOH = 15.0 g NaOH Ã #(1mol NaOH)/(40.00g NaOH)# = 0.375 mol NaOH. Calculate the number of litres of solution present. Volume = 225 mL Ã #(1L)/(1000mL)# = 0.225 L soln. Divide the number of moles of solute by the number of litres of solution.
