How many moles are in 1 gram of potassium chloride

0.0134 moles.

Explanation:

We will use conversion factors to solve this problem.

Potassium chloride has the chemical formula KCl.

1 gram of KCl is written on the left side of the conversion factor equation.

KCl has a molar mass of 74.5513 g/mol. This is found by adding together the atomic mass of each element. This means that 1 mole of KCl = 74.5513 grams

The conversion factor will look like this. To solve the equation we start with what is on the left, 1 gram. 1 is multiplied by the number in the numerator, and divided by the number in the denominator. When 1 is divided by 74.5513 it equals .0134. The unit grams cancel giving us our final answer in moles.

I hope this satisfied your request. Feel free to ask any questions. I apologize, my handwriting is a bit messy.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
