Honestly, thank you so much for this, I have never understood moles-I have been stressing over this topic for months and months and I just couldn't get it, but oh my life you explained it in such a simple, easy to understand way , I cant believe it but it is thanks to you I can finally say I can do moles. Thanks so much!!!! I am so HAPPY x

Maths is not my thing. Struggling with questions such as this: (c) Sodium hydroxide reacts with carbon dioxide. The equation for this reaction is 2NaOH + CO2 > NO2CO3 + H2O A solution of sodium hydroxide of concentration 2.00 mol/dm3 is used. (i) Calculate the amount, in moles, of sodium hydroxide in 200 cm3 of this solution and Deduce the maximum mass, in grams, of carbon dioxide that can react with this solution of sodium hydroxide. I think it is is the conversion between cm and dm that is confusing me? any advice would be greatly appreciated :/ :)

The formula for nitrogen is only N, not the entire (NH4)2, , so on the periodic table the mr of Nitrogen is 14, so therefore 14 x 2(because theres a 2 on the outside of the bracket) equals 28
