2. If a person cannot drink salt water, why can they drink sugar water? 3. Carrots were weighed, soaked in 4 different salt solutions and then re-weighed. Horace collected the weight changes (g) carefully: +2, -4,-1,0 Unfortunately, he forgot which weight change matched which salt solution. Predict which numbers should go where on the table below. Salt (g) added to 300 ml Weight change (g) water 10 20 5. In the table above, when the weight change is "O", the...
