Noticeably Absent Posted December 5, 2014 Report Share Posted December 5, 2014 HEY x.x So I am stuck here (attached photo) I and don't understand the last two questions(3 and 4)? I am supposed to write the equation? If so, where to I go from there? Also, in my background/theory for my lab report, it states that it should be a ratio of 1 to 1.

Your calculations in (1) & (2) are wrong:0.06 / 24.1 = 0.0025 (and not 0.004)0.042 / 16 = 0.0026 (and not 0.026) Hence for question 3, just take the ratio of the 2 results above by dividing 0.0026 with 0.0025 (as 0.0025 < 0.0026). We'll get about 1:1 ratioFor question 4, as the ratio is 1:1, then a molecule of magnesium oxide would contain 1 atom of Mg and 1 atom of Oxygen --> the formula is MgO Reply Link to post Share on other sites More sharing options...

Thank you! Wow, thank you so much Vioh, I understand the questions now! Reply Link to post Share on other sites More sharing options...
