Question
A typical solid fertiliser for use with household plants and shrubs contains the elements N, P and K in the ratio of 15g: 30g: 15g per 100g of fertiliser. The recommended usage of fertiliser is 14g of fertiliser per 5dm^3 of water. What is the concentration of nitrogen atoms in this solution?
-I don't get this question and don't know where to start from...
15+30+15=60 which means N,P,K are 60% of the component. How do we count 14g of the fertiliser since 14g is 14 out of 100?
