I can't figure out how to do this question: Given that the rate of energetic photons is striking Venus at about 10^30 per second and the age of the solar system is about 10^17 seconds, estimate the total mass of water that could have been lost from Venus since it formed. Th mass of a water molecule is 18 x 10^-27kg.(adsbygoogle = window.adsbygoogle || []).push({});

Any help will be much appreciated.

Edit: all I have figured thus far is that # of photons striking multiplied by charge of an electron gives the energy transfered to the H20 but how do I figure out how much is needed to dissociate the H20 and in turn how much H20 will be lost because of it?
