c 4. Ohe sand was not completely free of water when the mass was reported on the data sheet. ow does this affect the calculated percentage composition of the sand in the mixture?

c 3. If a student was unable to completely dissol e all the NaCl in the water, what effect would this ha e on the calculation of the percentage yield? Would the percentage yield be higher, lower or unaffected?cc O c cc cc c c ccc cc c c ccc c c c c c c c c c c c c c c c c cccc c c c c c c c
