Malathion is pediculicidal (kills live lice) and partially ovicidal (kills some lice eggs). A second treatment is recommended if live lice still are present 7â9 days after treatment. Malathion is intended for use on persons 6 years of age and older.
Molar mass is computed as the sum of the masses of all elements in the compound considering one mole of that substance. The mass of Ca is 40.08 amu while the mass of I2 is 126.9 amu. In the equation, there are 1 unit of Ca and 2 units of I2. Thus, (1 Ca x 40.08 amu) + (2 I2 x 126.9 amu) is equal to 293.88 amu.
The molar mass of a substance is its relative formula mass in grams. The unit for molar mass is g/mol. For example: the M r of water is 18, so its molar mass is 18 g/mol.the M r of calcium hydroxide is 74, so its molar mass is 74 g/mol.he molar mass is the relative formula mass of a substance in grams (measured in g/mol). Mass is conserved in chemical reactions, allowing the mass of a reactant or product to be calculated if the masses of the other substances in the reaction are known.
