What will the volume of a 0.50 M solution be if it contains .35 moles of calcium hydroxide?

What is the most important factor in determining climates.

Me soon im confused much mass would a mole of hydrogen molecules contain? recall that hydrogen is diatomic. g/mol

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
