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.
Molar mass is the weight of one mole (or 6.02 x 1023 molecules) of any chemical compounds. Molar masses of common chemical compounds that you might find in the chemistry laboratory can range between 18 grams/mole for compounds like water to hundreds of grams per mole for more complex chemical compounds.eport Abuse. The molar mass is simply the atomic mass expressed in grams (if your using gram moles, which I'm pretty sure you are). For example, take water, H2O: The atomic mass of water is 2 times the mass of H, plus 1 times the mass of O = 2*(1) + 1*(16) = 18 amu. So one mole of water is 18 grams.
