atomic mass of Mn = 55
total mass of Mn in molecule of protein = 3 * 55 = 165
1 mole of protein contains 165 g of Mn then
165 g is 0.818% of protein then molar mass of protein = 165*100/0.818
molar mass of protein = 20171.15 g/mol

One molecule of Mg3(PO302 contains atoms of Mg atoms of P atoms of O and has a molar mass of g/mol Which sample contains more molecules 35.2 g of glucose, CeH12Oe, 35.2 g of sucro C12H22O11, or do they have the same number of molecules?
In determining the identity of the protein that corresponds to a newly discovered gene, it often helps to know the pattern of tissue expression for that gene. For example, researchers have found that a gene called SERPINA6 is expressed in the liver, kidney, and pancreas but not in other tissues. What techniques might researchers use to find out which tissues express a particular gene?
Nitrogen forms a number of compounds with oxygen, for example nitrous oxide, N2O, is 6365% N by massA second compound, which contains two atoms of nitrogen per molecule, is 25.94 % N by mass. How many oxygen atoms are in the second compound?
As a researcher you are interested in characterizing a newly discovered protein. Based upon previous data you are convinced that the protein is a membrane protein. However, after sequencing the protein you discover that there are not large stretches of hydrophobic residues in the primary sequence. Based on this data which of the following statements is true? This data conclusively demonstrates that the new protein is not a membrane protein. This data conclusively demonstrates that the protein can only be...
