Find moles HCl.
5 g HCl (1 mole HCl/36.450 grams)
= 0.1372 moles HCl
Now, Molarity = moles of solute/Liters of solution
Molarity = 0.1372 moles HCl/1 liter
= 0.1372 M HCl
Then.
-log(0.1372 M HCl)
= 0.9 pH ( you might call it 1, but pH can be off the scale )

This is from the website linked to the left of this answer under Web Links:Solubility in water, g/100 ml at 20°C: 74.5Therefore, in 1 liter, 745.0 grams of CaCl2 will dissolve to make a saturated solution.
To prepare a 0.5 M glucose solution in 1 liter of water, you would need to dissolve 90.08 grams of glucose in enough water to make up the total volume of 1 liter. Start by weighing out 90.08 grams of glucose, add it to a container, and then add enough water to make the total volume up to 1 liter.
To make a 1 molar solution of sodium (Na), you would dissolve 23 grams of sodium metal into enough water to make 1 liter of solution. This would provide you with a solution where the concentration of Na ions is 1 mole per liter. Note that sodium is highly reactive with water, so the process should be done with caution.
One liter of a one molar solution of NaOH in water contains 40g of NaOH. The quantity must be known.
To prepare a 0.1N solution of NaOH, dissolve 4g of NaOH pellets in enough distilled water to make 1 liter of solution. This will result in a solution with a concentration of 0.1N of NaOH.

To make a 1 molar solution of sodium azide, you would need to dissolve 65.01 g of sodium azide in water to make 1 liter of solution. Since you have 98 mg of sodium azide, you would need to add enough water to make a final volume of 1 liter to create the 1 molar solution.
When a spoonful of sugar is added to half a liter of cold water, the sugar dissolves into the water, resulting in a sweetened solution. The sugar molecules break down and integrate with the water molecules, creating a homogenous mixture.

Mix this 50% solution in equal quantities with water(?) to halve it's strength. So use 1 litre of the 50% solution and 1 litre of water of that's what you are diluting it with.

This would provide you with a solution where the concentration of Na ions is 1 mole per liter. Note that sodium is highly reactive with water, so the process should be done with caution.
To determine the mass of the solution, we need to calculate the total mass of the solution when 81g of glucose is added. Since the solution is 15.0% glucose by mass, the remaining 85.0% is water. Therefore, the total mass of the solution can be calculated using the mass of glucose added and the percentage of water. This would result in a total mass of solution greater than 81g due to the addition of water to dissolve the glucose.

To prepare a 0.1N solution of NaOH, dissolve 4g of NaOH pellets in enough distilled water to make 1 liter of solution. This will result in a solution with a concentration of 0.1N of NaOH.

What volume of this solution do you desire? Let's say you want to make 1 liter of such a solution. You would weigh out 1 gram (1000 mg) of NaCl and dissolve it in enough water to make a final volume of 1 liter (1000 ml). Since 1000 ppm means 1000 mg/liter, this is how you make 1 liter of that solution. For larger or smaller volumes, adjust appropriately.
