Answer #1

0.198 % have 3 Cu atoms

0.198% of protein = 3 * 63.5 g

                                 = 190.5 g

them 100 % = (190.5 / 0.198) * 100

                        = 96212.21 g is molar mass of protein

A newly discovered metalloprotein, which contains three atoms of Mg per molecule of protein, is found to be 0.715% Mg by mass. Calculate the molar mass of the metalloprotein in g/mol. Hint: Another way of expressing that the metalloprotein is 0.715% Mg by mass is to say that 100 g of the metalloprotein contains 0.715 g of Mg. Start by determining the number of moles of Mg per 100 g of the metalloprotein.

A) Analysis of a volatile liquid shows that it contains 24.79 percent carbon, 2.04 percent hydrogen, and 73.17 percent chlorine by mass. At 268.0 °C and 1.6 atm, 652.0 mL of the vapor has a mass of 2.275 g. What is the molar mass of the compound? B) For the compound above, determine the molecular formula. Enter your formula as plain text, with carbon first, then hydrogen, the chlorine. So if the formula were C10H21Cl, you would enter C10H21Cl.
