How many hydrogen moles are in 2.5 moles of aspartame c14h18n2o5

Firstly, we need to convert 3g aspartame into moles aspartame. In order to do this we have to find the molecular mass of aspartame (the total weight of each atom of the molecule combined. This figure can be used to construct a conversion factor so that the grams may be converted into moles. Molecular weights for each atom can be found on any periodic table. Avagadro's number (6.022*10^23) is a constant value that expresses the number of molecules in one mole of a substance. 

The molecular weight for aspartame is 294.3 grams per mole. 

The process of finding how many atoms of H there are in 3.00g of aspartame would be like this: 

1. 3g * 1mol/294.3g = .01mol aspartame (this is converting grams to moles) 

2. .01mol * 6.022*10^23 = 6.022*10^21 (This is finding the number of molecules) 

3. (6.022*10^21) * 18 = 1.08*10^23 

This 3rd calculation is done because in part 2, you calculated the number of molecules of aspartame there were in 3g. In each molecule of aspartame there are 18 hydrogen atoms. So the final answer is: 
1.08*10^23 hydrogen atoms.

Product should she record in last row of the table

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
