A person takes a Ca-Mg-Zn pill daily. Zn can inhibit theabsorption of Mg. An intake of >142mg of Zn will prevent Mgabsorption. However, an intake of >500 mg of Ca can rescue Mgabsorption that is blocked by Zn. One dose of the supplementcontains 1.502 x 1022 atoms of Ca, 9.94 x1021 atoms of Mg, and 1.379 x 1020 atoms ofZn. With this information, answer the following:
A) How many doses of the pill is necessary to reach the Znthreshold which blocks Mg absorption?
B) The calcium in this pill is in the form of calcium carbonate,and only 15% of the calcium present in the dose will actually getabsorbed. Taking this constraint into account, is the level of Casufficient enough to rescue the Mg absorption that is blocked bythe Zn? Input the amount of Ca2+ absorbed.
C) There are 5 L of blood in the human body. Bloodconcentrations of Ca between 0.0035 and 0.0040 mol/L indicatecritical hypercalcemia. At this dose (the dose it takes to block Mgabsorption), will the calcium kill the person taking the pill?Answer here with the molarity of Ca2+ resulting fromingesting the number of doses calculated in question A.
