- Q3Why is it necessary to calculate the percentage change in mass before comparing the effect of concentration on the potato chips?The percentage is closer to the true value.Calculating the percentage is a more scientific measurement.Not all the chips have the same final mass.Not all the chips have the same initial mass.30s
