Asked by Jenny

18. What is the molecular mass of potassium hydrogen carbonate (KHCO3)?
A. 116 g/mol
B. 68 g/mol
C. 100 g/mol
D. 84 g/mol

My guess would be A? I got 110.1, but that's not an option.

My! Your identity crisis looks serious. You've posted 9 chemistry questions, using three different names -- Hannah, Kaylee, and Jenny.

Please use only one name for your posts.

Oh it is. It's especially bad when people waste my time with their replies that are of no use to me :)
