How do you calculate the molar mass of a chemical compound? For example, suppose you have a 42.65-gram sample of lead(II) nitrate, Pb(NO3)2. Calculate the mass in grams of 0.425 moles of tin(IV) nitrate. Write the formula and calculate the molar mass of copper(II) nitrate. ...
Molar Mass: The molar mass of a compound pertains to the mass that constitutes one mole of the compound. It can be computed by adding the molar masses of the elements making up the compound. The subscripts of each element in the chemical formula are multiplied ...
There are other easy ways to express the concentration of a chemical solution. Parts per million and parts per billion are used primarily for extremely dilute solutions. g/L= grams per liter = mass of solute / volume of solution F= formality = formula weight units per liter of solution ...
