So we already have. All of these materials are pretty for us. You know that a gas is gonna be we, um, times longer than humans. So what about three divided by one and then by just looking at a PR people we know that the molar mass of a G is four grams per mole. So now that we have that all clothed in, we just need to solve for the molar mass of
