Percent by mass is another way of expressing concentration in mixtures. It would be mass of a substance per mass of the mixture times 100 percent. We calculate as follows:

Percent by mass NaCl = 5.6 g / 125 g x 100 = 4.48%

Hope this answers.

10.The electroscope is a fairly simple device comprised of a metal rod with two thin leaves attached to one end. If the electroscope is given a negative charge, the metal leaves will separate from each other. It is this characteristic that makes the electroscope useful as a detection device. A negatively charged electroscope will discharge when ions in the air remove electrons from it, and consequently, a positively charged electroscope will discharge when it takes electrons from the air around it. The rate of discharge of the electroscope is a measure of ions in the air and can be used as a basis of measurement and detection
