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 mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbonâs molar mass is 12.011 g/mol, and magnesiumâs molar mass is 24.3050 g/mol.he number of grams in the molar mass of an element is the same as the atomic mass. Translating atomic masses into molar masses, you can construct conversion factors that convert between the mass of an element and the number of moles of the element.
