Question 986177: Some amount of coals weighed 100 kg and contained 14.5% water. After some time evaporating, the water was 10%. What was the ratio of the weight of the coals now to the weight of the coals before evaporation? Answer by solver91311(24713) (Show Source):
Not without knowing something about the relative density of water and coal. This is a chemistry problem, not an algebra problem. You are on the wrong website.
