Please show how to do each step
LAB: MassPercent
1-Weigh approximately 5 g NaCl on weigh paper and add to a 250ml Erlenmeyer flask. Record the exact mass here (The mass is 4.85 g)
2-Using a 100 ml graduated cylinder, add 100 ml water to theflask and stir until the solute has dissolved. Calculate theconcentration in mass percent of this solution assuming the densityof the water is 1 g/ml.
Solution + flask =227.747 g
Flask =81.565 g
3-Transfer 60.0 ml of the NaCl solution using a 100 ml graduatedcylinder to a PREVIOUSLY weighed 150 mlbeaker. The mass percent of the solution in the beaker is_______________.
The beaker mass is 93.469 g
4-Weigh the beaker with the 60 ml solution sample and record themass here _153.623 g. Calculate the mass of solution as well as themass of solute in the beaker.
5-Transfer 40.0 ml of the NaCl solution from the Erlenmeyerflask to a PREVIOUSLY weighed 150 mlbeaker. Don’t forget to weigh the beaker before adding the NaClsolution to it. Record the mass of the beaker is 93.495 g. The masspercent of this solution in the beaker is _______________.
6-Weigh the beaker with the solution and record the mass here133.790 g. Calculate the mass of solution as well as the mass ofsolute in the beaker.
7-Compare the masses of the solutions and solutes in each beaker(calculated values in numbers 4 and 6) with their respectiveconcentrations.
