What is the mass of nickel(ii) nitrate (182.71 g/mol) dissolved in 25.0 ml of 0.100 m ni(no3)2 solution?

Answer : The mass of nickel(II) nitrate is, 0.4568 grams

Explanation : Given,

Molar mass of nickel(II) nitrate = 182.71 g/mole

Volume of solution = 25.0 ml

Molarity = 0.100 M

Molarity : It is defined as the mass of solute present in one liter of solution.

Formula used :

where,

w = mass of nickel(II) nitrate

M = molar mass of nickel(II) nitrate

V = volume of solution

Now put all the given values in the above formula, we get:

Therefore, the mass of nickel(II) nitrate is, 0.4568 grams
