How do you prepare 3 ppm solution of ferric chloride in 1000 liter water?
Just take 3 grams and add this to 1000 litres (= 1,000 kg = 1,000,000 (million) grams)
How many grams of a drug must be used to prepare 3 liters of a 2 percent solution?
To prepare a 2% solution in 3 liters, you would need 60 grams of the drug. This is calculated by multiplying the volume (3 liters) by the percentage (2%) and converting the result to grams. 3 liters x 2% = 60 grams.
How do you make 3 normal barium chloride?
To make a 3 M solution of barium chloride (BaCl₂), first calculate the required amount of BaCl₂ by using the formula: mass = molarity × volume × molar mass. The molar mass of barium chloride is approximately 208.23 g/mol. For example, to prepare 1 liter of a 3 M solution, dissolve 624.69 grams of barium chloride in enough water to make the total volume 1 liter. Always ensure to wear appropriate safety gear and follow proper lab protocols when handling chemicals.
What is the percent composition by mass of iron in iron (III) chloride?
To calculate the percent composition by mass of iron in iron (III) chloride (FeCl₃), first determine its molar mass. The molar mass of Fe is approximately 55.85 g/mol, and for Cl, it is about 35.45 g/mol, giving FeCl₃ a total molar mass of approximately 162.2 g/mol (55.85 + 3 × 35.45). The percent composition of iron is then calculated as (mass of Fe / molar mass of FeCl₃) × 100, which is (55.85 / 162.2) × 100 ≈ 34.4%. Thus, the percent composition by mass of iron in iron (III) chloride is approximately 34.4%.

How many chloride ions are there in 3 mol of aluminum chloride?
Aluminum chloride contains 3 chlorine atoms per molecular unit. Therefore, in 3 moles there are 3 times Avogadro's number of chloride ions = 1.807 X 1024.
