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.
This number, Avogadro's number, is 6.022x10 23. The mass in grams of one mole of a compound is equal to the molecular weight of the compound in atomic mass units. One mole of a compound contains 6.022x10 23 molecules of the compound.The mass of 1 mole of a compound is called its molar weight or molar mass.The units for molar weight or molar mass are grams per mole. Here is the formula for determining the number of moles of a sample:ne mole of a compound contains 6.022x10 23 molecules of the compound. The mass of 1 mole of a compound is called its molar weight or molar mass. The units for molar weight or molar mass are grams per mole.
