How many milligrams of an active ingredient are needed to make 400 ml of a 1 in 1000 solution?
It is not clear whether the strength of the solution is given in terms of mass/mass or volume/volume (or mass/volume). Without that information, it is not possile to answer the question.
Depending on which one you may need the density of the active ingredient or of the solvent to convert between mass and volume of that component.

What is the procedure to extract an active ingredient from a plant?
To extract an active ingredient from a plant, first, select and prepare the plant material by drying and grinding it if necessary. Next, choose an appropriate solvent (such as water, ethanol, or methanol) and immerse the plant material in it, allowing for extraction through methods like maceration, percolation, or refluxing. After a specified period, filter the mixture to separate the liquid extract from the solid residue. Finally, concentrate the extract if needed, and analyze it to identify and quantify the active ingredient.

How would you know the milligrams per weight in animal penicillen?
The bottle will state how many milligrams there are per milliliter. The instructions included with the bottle will say how many milligrams per kg are needed for the species of animal to be treated. With that info you can calculate the number of milligrams you will be administering.
What is the first ingredient needed for a tornado to develop?
The first ingredient needed in instability, which occurs when the lower atmosphere is warm and moist while the upper portion is cold and dry. Instability is what drives thunderstorms.
How many milligrams of MgI2 must be added to 200.0mL of 7.72102M KI to produce a solution with I 0.1000 M?
To find out how many milligrams of MgI₂ are needed, first calculate the total moles of I⁻ required for a 0.1000 M solution in 200.0 mL. This amounts to 0.1000 M × 0.200 L = 0.0200 moles of I⁻. Since KI provides one I⁻ per formula unit, the moles of I⁻ from KI is 7.72102 M × 0.200 L = 1.5442 moles. Therefore, the deficit of I⁻ is 0.0200 moles - 1.5442 moles = -1.5242 moles. Since the solution already exceeds the requirement, no MgI₂ is needed. In summary, no MgI₂ needs to be added because the existing KI provides more I⁻ than required.

What volume of NaOH solution (in mL) is needed to neutralize a given acid solution?
To determine the volume of NaOH solution needed to neutralize an acid solution, you would need to know the concentration of the acid solution and the volume of the acid solution. Using the equation n1V1 n2V2, where n represents the number of moles and V represents the volume, you can calculate the volume of NaOH solution needed.
