The IUPAC name of PbCl4 is lead tetrachloride, an inorganic compound. The acronym IUPAC stands for the International Union of Pure and Applied Chemistry, which is a federation of chemists that create the chemical names of different substances.
To find the number of moles in I2, we have to know the atomic weight of iodine (which my periodic table tells me is 127). But iodine is a diatomic element, existing in molecules of 2 iodine atoms bound together (I2). So the molecular weight of I2 is 2 x 127 = 254g/mole. Moles = mass/MW, so moles = 450g/(254g/mole). The "grams" cancel out and the answer is 1.77 moles.
Use dimensional analysis to solve this problem. First calculate the molecular mass of CO2. This is found by (use a periodic table) adding 12.011g of C to (15.999g x2) grams of Oxygen. Once you do that, you find out that 44.009g are in 1 mole of CO2. Now, simply by looking at the equation of CO2, we can tell that 2 moles of oxygen atoms are in 1 mole of Co2 (look at the subscript for Oxygen). Now, your dimensional analysis should look like this: 254g CO2 x 1 mole CO2/44.009g CO2 x 2 mole Oxygen/1 mole CO2 The answer is 11.5 moles of Oxygen in 254g of CO2.
