Mar 27, 2015 · If we use 16 g of Mg with a molecular weight of 24 g/mol, then we have (16 g)/(24 g/mol) = 0.66 mol of Mg. According to our balanced reaction above, we need half this number of moles of CO 2 = 0.33 mol. Given a molecular weight of 44 for CO 2, that is (0.33 mol)(44 g/mol) = 14.67 grams, roughly a half-ounce. "Ah!" you say. "What about all the HEAT?
Sep 23, 2006 · In mole of MgCO 3, one would have 1 mole of Mg, 1 mole of C, and 3 moles of O. Mass wise, one would have 24.3 g of Mg, 12 g of C and 48 g (3 x 16 g) of O, which gives a mass of one mole of MgCO 3 as 84.3 grams. That gives a ratio of 24.3 g Mg/84.3 g MgCO 3 = 0.288 g Mg/ g MgCO 3. 3.96 g * 0.288 = 1.14 g, which is the answer one obtained. Magnesium Chlorate Mg(ClO3)2 Molar Mass, Molecular Weight. Mg(ClO3)2 is a white powder at room temperature. It is soluble in water.
