Biological enzymes often incorporate metal ions for the purpose of carrying out electron transfer and oxidation reactions. If a particular enzyme incorporates 3 Fe atoms, and the metal atoms account for 0.22% of the overall mass of the enzyme, what is the molar mass of the enzyme

In a spacecraft, the following reaction occurs: co2(g) + 2lioh(s) -> lico3(s) + h2o(i) (i attached picture of equation) how many liters of carbon dioxide will 4 moles of lithium hydroxide (lioh) absorb? (one mole of any gads occupies 22.4 l under certain conditions of temperature and pressure. assume those conditions for this equation.) 45l 6.0l 3.0l 34l

If a solution contains 3 moles/liter of sodium chloride (nacl, made of sodium ions and chloride ions), what is the osmolarity of this solution
