Calculate the mass % of nacl in a solution containing 1.5g of nacl in 50.0g of water
100(1.5 / 50) = ________ %
To calculate the mass % of NaCl in the solution, we need to determine the mass of NaCl and the mass of the entire solution.
1. First, let's find the mass of NaCl:
We're given that there is 1.5g of NaCl in the solution.
2. Next, let's find the mass of the entire solution:
We're given that there is 50.0g of water in the solution.
3. Now, add the masses of NaCl and water together:
Mass of solution = mass of NaCl + mass of water
Mass of solution = 1.5g + 50.0g
4. Calculate the mass % of NaCl:
Mass % of NaCl = (mass of NaCl / mass of solution) * 100%
Mass % of NaCl = (1.5g / (1.5g + 50.0g)) * 100%
5. Simplify the equation:
Mass % of NaCl = (1.5g / 51.5g) * 100%
6. Calculate the final answer:
Mass % of NaCl = 2.91%
Therefore, the mass % of NaCl in the solution is approximately 2.91%.
