Metals present in municipal waste water may still be present in treated sewage sludge IN CONCENTRATIONS THAT MAY AFFECT THE PUBLIC HEALTH. Sewage sludge is an end product of municipal waste water treatment and it contains many of the pollutant that are removed from the waste water.
multiply the number of each atom with its molecular mass. (see the periodic table)
5*12 + 12*1 = 72 gram per mole.
Or more accurately: 5*12.01078 + 12*1.007947 = 72.149264 g/mole
Answer:
Greater
Explanation:
According to the law of universal gravitation, the force of gravitation is directly proportional to the product of the masses of the two objects and INDIRECTLY proportional to the square of the distance. In short, the bigger the masses, the stronger the gravitational force, the lesser the distance between the two objects, the greater the gravitational force.
