13. This means every molecule of magnesium … The formula for magnesium oxide is MgO. A gas mixture contains 1.05 mol of O2 and 5.21 mol of N2. Relevant information: Magnesium Fluoride: MgF2. 2. Molar mass of MgCl2 = 95.211 g/mol (Mg: 24.3050 g/mol , Cl: 35.453 g/mol *2) mass of 3.80 moles of magnesium chloride = 3.8 mol * 95.211 g/mol = 361.8018 g Mass of F = 18.9984032 g/mol. d) all of the above. How many grams are in 1.40 mol of sodium chloride (NaCl) 3. The helium balloon has more atoms. One mole is 6.02x10^23 molecules of that compound. In comparing a balloon containing 25 grams of helium to a balloon containing 25 grams of neon, which one of the following statements is TRUE? 1. In a gas mixture composed of O2, Ne, and He, the partial pressure ofO2 is 0.90 atm, that of Ne is 3.1 a … tm, and that of He is 1.50 atm. . Got me! b) molecules in one mole of O 2. c) marbles in one mole of marbles. Whatis the total pressure of the mixture?2. What is the mass of 7.50 moles of magnesium chloride, MgCl2? A single molecule of a certain compound has a mass of 3.4x10-22 g. Answer: D. 107 g. Given: 1.72 mol MgF2. Mass of Mg = 24.3050 g/mol. Dalton's Law of Partial Pressure1. Mass of MgF2 = Mass of Mg + 2(Mass of F) = 24.3050 g/mol + 2(18.9984032 g/mol) = 62.3018064 g/mol Molar mass is the mass of one mole of a compound. No Magnesium Sulfate (MgSO4) has a mass of 121, and Sodium Chloride (NaCl) has a mass of 59. A) the mass of half a mole B) the mass of one mole C) the mass of one molecule D) the mass of one atom B) the mass of one mole A sample of calcium that contains Avogadro's number of atoms has a mass of ________. The molar mass of an element is its atomic weight (relative atomic mass) on the periodic table in g/mol. After you do that, you could see if your summation is right. its molar mass. The atomic weight of magnesium is 24.305, therefore its molar mass is #"24.305 g/mol… The idea here is that you need to use the chemical formula for magnesium nitride ##Mg_3N_2## to calculate the mass of one mole of the compound i.e. I know that 1 mole of magnesium has a mass of 24.3 g. And I know that 1 mole of nitrogen has a mass of 14.01 g, and that 1 mole of oxygen has a mass of 15.99 g. Do you think that by adding the masses together, appropriately weighted, i.e. The mass of 1 mole of magnesium is greater than the mass of 1 mole of carbon. How many molecules of … 1xxMg + 2xxN + 6xxO, you would arrive at the formula mass of Mg(NO_3)_2? The number of atoms in 9.0 g of aluminum is the same as the number of atoms in a) 8.1 g of magnesium b) 9.0 g of magnesium c) 12.1 g of magnesium d) 18.0 g of magnesium 14. So magnesium nitride is an ionic compound made up of magnesium cations ##Mg^(2+)## and nitride anions ##N^(3-)##.
