what mass of Nacl and H2o are present in 160.0g of 12 mass percentage solution of Nacl?
To determine the mass of NaCl and H2O present in a 12% mass solution of NaCl, we need to understand that a 12% mass solution means that 12g of NaCl is present in 100g of the solution.
First, we need to determine the mass of NaCl in the given solution.
Mass of NaCl = (Percentage of NaCl / 100) * Mass of solution
= (12 / 100) * 160g
= 19.2g
Next, we need to calculate the mass of water (H2O) in the solution.
Mass of H2O = Mass of solution - Mass of NaCl
= 160g - 19.2g
= 140.8g
Therefore, in a 160g 12% mass solution of NaCl, there would be approximately 19.2g of NaCl and 140.8g of H2O.
