Given the starting solution had a concentration of 1.25 m, how many moles of co[h2o]6cl2 were available in the amount of starting solution you used

Molarity of solution is defined as number of moles present in one liter solution. Mathematically, it is expressed as 
Molarity = 

Thus, if 1 mole of solute is present in 1 liter solution, molarity of solution is 1 M.

In present case, initial conc, of solution was 1.25 M.

∴ Number of moles of co[h2o]6cl2  available initially = 1.25 mole, if the solution is 1 liter

It's a
