Asap read the balance and use this data to determine the density of a sample. the sample displaced 65.6 ml of water. mass = g density = g/cm3

Mass of the of sample using the balance is 433.2 g
You can estimate the decimal part because it not exactly 3
400 + 30 + 3.2 

To find the density of the sample you divide mass / volume = density

Mass = 433.2 and Volume = 65.6ml                433.2 g / 65.6
                                                                                 
                                                                             6. 6 g/ml^3    
 
 Density = 6.6 g / ml^3   and Mass = 433.2 g                                        

The formula is (nh4)2co3

Conservation efforts have been effective in "increasing the number of endangered species, reducing all the negative impacts of human activity, and preserving wildlife habitats".hope my answer has you : )
