A 1.268 g sample of an alkaline earth metal carbonate, MCO3 was treated with 100.00 mL of 0.2166 M HNO3, as shown in the reaction below. After the reaction, it was determined that 8.809 × 10－3 moles of HNO3 remained in solution. Given this information, what is the identity of the metal M? Show all of your work.

MCO3(s) + 2HNO3(aq) → M(NO3)2(aq) + CO2(g) + H2O(l)

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.

50.23 i believe is correct but don't quote me on that.
