1 Answer

Answer :

I'll try, I just don't know if I'm allowed to contribute. In your case, these are weight percentages. Weight percentages indicate the number of grams of solute in 100 grams of solution. Thus: 3 g of carbonate + 97 g of water gives 100 g of 3% carbonate solution x 2.5 .................. 7.5 g of carbonate + 242.5 g of water gives 250 g 3% sodium carbonate solution I don't know why I don't want to print in bold.
