mole NaCl = 0.0927
mole H2O = 1.0000 - 0.0927 = 0.9073
then
mass NaCl = 0.0927mole x (0.9073g / mole) = 0.1022 g
mass H2O = 0.9073 mole x (18.02g / mole) = 16.35 g
and therefore;
mass % NaCl = [(0.1022g NaCl) / (58.45g NaCl + 18.016g H2O)] x 100% = 24.9%
=24.9%
In 1668, Francesco Redi proposed a different hypothesis about the appearance of maggots. He thought that flies laid eggs on the meat, but the eggs were just too small for people to see. He thought that the eggs then developed into maggots. hope this helps :)
Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Sulfur dioxide (SO2) emissions, primarily the result of burning coal, contribute to acid rain and the formation of harmful particulate matter.
