26,4 g iridium is equal to 0,137 mol.
1 Mol
~58 If iridium has a density of 22.42 g/cm3, 1300 grams of iridium would displace 1300/22.42 grams of water (as water has a density of 1 g/cm3). The shape of the iridium is irrelevant.
16 grams of oxygen how many moles is 0,5 moles.
moles of what?
2 moles of Ca and 4 moles of OH
1 Mol
34
Iridium, Einsteinium
2
Of course 6 moles.
there are 4.5 moles
16 grams of oxygen how many moles is 0,5 moles.
Lead has a higher atomic number than iridium, which means a lead atom is heavier than an iridium atom. however iridium is denser, therefore if you had a block of iridium and a block of lead,the iridium block would be heavier
