If 75 g of active ingredient powder is mixed with 400 ml ns solution, what is the final concentration round to the nearest hundredths (w/v)?

0.19g/mL

Step-by-step explanation:

The concentration of a solution is how much of a substance in in another substance, usually the amount of solute in a solvent.

The solute is the active ingredient powder. The solvent is the NS solution.

Divide the solute by the solvent.

75g ÷ 400mL

= 75g/400mL     Simplify for solute per one unit, 1 mL. Divide top by bottom.

= 0.1875g/mL   Round to the nearest hundredth, second decimal place.

≈ 0.19g/mL

Therefore the final concentration is 0.19g/mL.

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
