Table 2.3. The density of liquids Liquid Volume, mL Mass, g Density, g/mL Water 50 77 - 27 = 50 Saturated Salt Solution 50 83 - 27 = 56 6. Calculate the densities of the liquids in Table 2.3. The accepted density of water is 1 g; cm. How do your results compare? Remember that 1 cm = 1 mL.​

What are the similarities of physical and chemical change ?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
