Does Oil of Oregano raise the sugar in your blood? !!!!!©LaBrake!&!Vanden!Bout!2013! 输入计算其摩尔质量和元素的组合物的化学式: 摩尔质量 of CF2Cl2 is 120.9135 g/mol Convert between CF2Cl2 … Revised!CS9/16/13!!!!! Calculate the root-mean-square velocity of Freon-12 molecules in the lower stratosphere where the temperature is –65°C. Calculations: Formula: CF2Cl2. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. What are the release dates for The Wonder Pets - 2006 Save the Ladybug? Dichlorodifluoromethane (R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant. Comments. Now, convert your mass into grams: 26.2 mg X (1 g/1000 mg) = 0.0262 grams Next divide the mass by the molar mass to give you moles: 0.0262 g / 207 g/mol = 1.27 X 10^-4 moles Cl 2 35.453 58.64%. Calculate the mass of 3.00 moles of CF2Cl2? Formula: CF2Cl2. Molar Mass: 120.913 g/mol 1g=8.27040930255638E-03 mol. How … F 2 18.998 31.42%. The chemical equation is already balanced. Molar mass of CF2Cl2 = 120.9135064 g/mol. so 25g/ 1 month * 12 months / 1 year= 300g per year. 1) Molar mass of CF2Cl2, MM = 1*MM(C) + 2*MM(F) + 2*MM(Cl) = 1*12.01 + 2*19.0 + 2*35.45 = 120.91 g/mol mass(CF2Cl2)= 38.8 g use: number of mol of CF2Cl2, n = mass of CF2Cl2/molar mass … 3.00 mol x 122g/mol (cancel out the moles as units) =366g.
