How to prepare a 50liters of sea water solution of NaCl how much NaCl is required in gram?
The concentration of NaCl in sea water is about 35 g per kg. The density of seawater is about 1.025 kg/l, so you would need 50 * 1.025 kg sea water for 50 liters of solution.
NaCl contributes to this with 35 * 1.025 * 50 g / kg * kg / l * l. consequently the result is about 1794 g of NaCl.

What Calculate mass of potassium chloride required to prepare its 40 solution in 100g of water?
To prepare a 40% potassium chloride solution in 100g of water, you would need to calculate the mass of potassium chloride required. Since the solution is 40% potassium chloride, that means 40g of the total solution mass must be potassium chloride. Therefore, you would need to add 40g of potassium chloride to the 100g of water to prepare the solution.

How do you prepare 0.05N of HCl?
To prepare 0.05N HCl solution, you would need to calculate the amount of concentrated hydrochloric acid solution (typically 37% concentration) needed to dilute with water to get the desired concentration. Measure the appropriate volume of the concentrated acid and dilute it with the required amount of water to achieve a final volume of 1 liter.
How do you prepare 2 ppm solution of nickel nitrate?
To prepare a 2 ppm solution of nickel nitrate, you would dissolve 2 grams of nickel nitrate in enough water to make 1 liter of solution. This will result in a solution where there are 2 parts of nickel nitrate for every 1 million parts of water.
How much NaOH required for 1 normal solution?
To prepare a 1 normal solution of NaOH, you would need to dissolve 40.00 grams of NaOH in enough water to make 1 liter of solution. This is because the molecular weight of NaOH is 40 g/mol.
