What is the molarity of potassium ions in a 0.122 m k2cro4 solution

 The molarity   of potassium  ions  in a 0.122 M  K2CrO4  is 0.244 M

Explanation

write dissociation reaction  for K2CrO4

that  K2CrO4 (aq)→ 2K^+ (aq)  + CrO4^2- (aq)

K2CrO4  dissociate to give  2  ions of potassium ,therefore  the molarity  of potassium ion = 2 x 0.122  = 0.244 M

b) mutualism

hope this : )

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
