The number of moles of moles of Magnesium,chlorine and oxygen atoms in 7.80 moles of Mg(ClO4)2 is calculated as below
find the total number of each atom in Mg(ClO4)2
that is mg = 1 atom
Cl = 1x2 = 2 atoms
O = 4 x2 = 8 atoms
then multiply 7.80 moles with total number of each atom , to get the number moles of each atom
that is
Mg = 7.80 x1= 7.80 moles
cl = 7.80 x2=15.6 moles
O = 7.80 x8= 62.4 moles
<span>El Niño during the time of 1997 to 1998 caused drought in Southeast Asia and flooding in much of Latin America and in the Horn of Africa due to significant amounts of rainfall. The effects in both places were numerous deaths. In areas where it flooded, mudslides occurred and spoiled seed stores. In areas of drought, crops were extremely diminished and let to starvation.</span>
