In dilute solutions, the unit osmolarity is being used. It usually has units milliosmols per liter of solution or mOsmol/L. An osmole defines the number of moles of the solute that would have an effect on the osmotic pressure of the solution. Osmolarity is calculated by the product of the molarity and the number of particles in the solution which is 2 for potassium chloride. We calculate as follows:
Osmolarity = molarity (# of particles)250 mosmol/L ( 1 osmol / 1000 osmol) = x moles / .100 L (2)
x moles = 0.0125 mol KCl
mass KCl = 0.0125 mol KCl ( 39 + 35.5 g/mol) = 0.93125 g KCl
Answer: This is the definition if that's what you want.
Explanation:The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity can neither be added nor be removed.
Answer:
Hey weirdo what's up?
So you got a question huh?
Lemme answer
As said the correct reading is 3.0grams
And the option A has 3.01 and 2.99 which are very mush precise and accurate to 3.0 gram don't you think?
So the answer is
Option ii the result of students A is both precise and accurate
Loye ya
Peace out
