<span>Mass percentage is one way of representing the concentration of an element in a compound or a component in a mixture. </span>To calculate percent by mass, you need to determine two things: the mass of just the element, and the molar mass of the whole compound. We calculate as follows:
.10 g NaCl / g NaCl + Water = ( 10.0 g NaCl + x ) / (10.0 g + 255 g + x )
x = 18.33 g NaCl needed

Answer: The length of the tropical parasite insect in centimeters is 9.3 cm.
Explanation: We are given the length of the parasite insect in milimeters and we need to convert it into centimeters. So, for that we use the conversion:
