The result you obtained during measurement is in mg element per liter of the solution examined. If you've measured original sample, without any previous preparation and/or dilution, the result obtained is the final one (mg/L = ppm). If you've prepared your sample prior to analysis, some additional calculation is needed.
Assume, that you digested 500 mg of the soil in acid, and the final volume of your sample is 25 ml. The solution was measured on ICP-AES and 0.5 mg/L Cu was found. How much Cu the soil contains?
25000 microliter / 500 mg (or 25 ml / 0.5 g) = 50. This is your dilution factor. Multiply your measured result by this factor
0.5 mg/L Cu * 50 = 25 mg Cu per 1 kg of the soil.
Of course, if you diluted your digested sample during the measurement, this dilution factor also must be taken into account.
The rate of a reaction is calculated using the concentrations of reactants.

By amount I assume you mean moles. The amount of moles per liter and the amount of moles are the same if you calculate from 1 L (which is what you do when you have, for example, 0,30 M) 0,30 M = 0,30 mol/liter, if you have 1 liter that means you have 0,30 moles. So you can use either moles or mol/liter.

pure water no impurities,,so that cannot disturb the result of the experiment
The context for an osmosis experiment typically involves studying the movement of water molecules across a semi-permeable membrane. It aims to investigate how concentration gradients affect the direction and rate of water movement, and how different solute concentrations impact osmotic flow. The experiment can be conducted using various materials, solutes, and concentrations to observe and measure the osmotic process.

A Landmark experiment using the scientific method is... Research it for yourself!!!!

To make sure your results are Valid/reliable. You should always repeat your experiments and if using times or amounts and in the future going to make a graph its best to do the experiment 3 times and calculate the average on place the average result on to your graph.
