in number two. We have oxygen that has a atomic ms of 15.999 You We're supposed to convert that kilograms and also to its energy equivalent. So I'm just gonna Ugh factor label. Let's start with what I'm given 15.999 atomic mass units. And I know that one Atomic Miss Unit is the same as 1.66 I better keep a lot more significant figures here. 1.66 056 times 10 to the negative, 27 kilograms. So you canceled and like 2.6 five 67 times, 10 to the negative 26th kilograms. And then I want to convert that to the equal energy. Also, one U is the same as 931 0.494 mega electron volts over beetle. It's good. So you canceled and I get 14,000 903 mega electron volts over C squared
