The solute is the material you're dissolving into your solution; in this case the ammonium chloride. 0.341 M (molar) means you need 0.341 mol/L.
500mL = 0.5L, so to make 500 mL of solution you actually need 0.5*0.341 = 0.1705 moles of ammonium chloride.
ammonium chloride weighs 53.491 g/mol (14.0067+1.00794+35.453, all the molecular weights of the elements in NH4Cl)
0.1705*53.491 = 9.12 grams
The morality of the solution is roughly 2.5 mols per liter.
Take 5 grams of calcium chloride and dissolve it in 100ml of solution to get a 5% solution of calcium chloride. The standard way to make a weight-volume solution is to take grams of the dry substance in 100ml of volume.
add 5 ml of 37% HCl to 495 ml Water. This is 0.12 N ;)

Solubility increases with temperature, but the solubility of sodium chloride in water is 316 grams per litre at 0 degrees Celsius, and 330 grams per litre at 70 degrees Celsius. Since room temperature is somewhere between these two, this gives upper and lower limits of the solubility at room temperature. 50 grams of water has a volume of 50 cubic centimetres, or 0.05 litres. In one litre you could dissolve between 316 grams and 330 grams, so in 0.05 litres you could dissolve between 15.8 and 16.5 grams, where 15.8 = 316 x 0.05 and 16.5 = 330 x 0.05. So we can say it's around 16 grams of NaCl in 50 grams of water at room temperature.

Yes, this is exactly it. If you don't have a litre, it is still a certain molarity solution, provided you know the amount of moles. For example. 2 moles in 500ml. If there are 2 moles in every 500ml, there will be 4 moles in every 1000ml, i.e. 4 molar.
500mL is 0.0005m3
Divide by 1000 500ml=0.5L
50L is bigger than 500ml
500ml an hour
Flow rate of 500mL over 4 hours = 500mL/4h = 125mL/h
5l is greater than 500ml
500ml/1000ml(1l)=1/5
A person is dehydrated and is given 500 ml of normal saline.how many grams of sodium chloride will person recieve ?
500ml is 0.5Litres, approx. a medium sized water botttle.
30% more than 500ml = 650ml.
