how many grams of potassium hydroxide, koh would be dissolved in 250ml of a 0.10m solution of potassium hydroxide? 2. what is the nitrate ion concentration, [no3 1] - , in 100.ml of magnesium nitrate solution, mg(no3)2, that has 2.5g dissolved magnesium nitrate?

Concentration is the abundance of a constituent divided via the total quantity of an aggregate. numerous kinds of mathematical descriptions may be outstanding: mass awareness, molar concentration, variety concentration, and extent attention.

The amount of a substance, inclusive of salt, that is in a positive amount of tissue or liquid, including blood. A substance will become extra focused while less water is present. An excessive concentration of a substance in a solution approach that there's a number of it relative to the quantity: the high-quality Salt Lake has only a few fish because of the excessive awareness of salt.

250 cm³ = 0.25 dm³ = (0.25 L)

For solution C = n/v

n = CV

= 0.10 × 0.25

= 0.025 mol

The molar mass of potassium hydroxide is = 56

mass = molar mass × mol

= 56 × 0.025

= 1.4 grams.
