Active mass of 5.6g Cao(s) is |
|
Answer» ACTIVE mass of a substance is its molar concentration or molarity. Means, NUMBER of mole of substance per litre of solution is known as active mass of substance. so, active mass of CaO = molarity of CaO given WEIGHT = 5.6 g molecular weight = 56g so, number of mole of CaO = 5.6/56 = 0.1 LET 5.6 g of CaO in 1L of solution then, active mass of CaO = 0.1/1 = 0.1 mol/L |
