What is the molarity of a solution prepared by dissolving 15.0g of sodium hydroxide in enough water to make a total of 225 ml of solution

1.6666 g/mol = 1 g/mol

Explanation:

Molar mass of NaOH= 23+16+1 =40g/mol

Mols in 15g = 15/40 mol

If this was dissolved in 225ml of water molarity of the solution is

÷ 225 x 1000 = 1.6666 g/mol = 1 g/mol

the best that can be interferred in this except is that molina has taken up the cause of abused and disadvantaged kids through his foundation. and that the chance to live up to clemente's legacy was a motivating factor for him to continue defending those who are in an unfavourable possition.
