Greenhouse gases are more efficient at absorbing thermal energy and re-radiating it than the other atmospheric gases.
First calculate the number of moles of CaBr2 given the
molar mass of 199.89 g/mol.
moles CaBr2 = 0.9182 g / (199.89 g / mol) = 4.60 x 10^-3
mol
We see that each CaBr2 contains only 1 mole of Ca, so the
moles of Ca is also:
moles Ca+ = 4.60 x 10^-3 mol
So the molarity of this is:
Molarity Ca+ = 4.60 x 10^-3 mol / 0.500 L
<span>Molarity Ca+ = 9.19 x 10^-3 M</span>
