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? a) 157 g b) 0.250 g c) 4578 d) 0.4578 e) 4.00 g

0.4578 g

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,

n= moles of solute

= volume of solution  in ml = 25.0 ml

Thus 0.4578 g of nickel(II) nitrate is to be dissolved in 25.0 mL of 0.100 M solution.

gravity causes stares to cluster i think so
