Circle your final answer. 119.05g-26.53g = 90.52g D2 Density is calculated by dividing the mass of a sample by Its volume (d = ). Calculate the density of the water sample. Show all work with units and correct significant figures. Circle your final answer. d: 117.059. 50 ml 2.341 =2.391mL. Compare your calculated density to the known value of 1.00 g/ml. by using the % difference equation shown below. How close is your value to the known value?

Compare your calculated density to the known value of 1.00 g/mL by using the % difference equation
shown below. How close is your value to the known value? (If your calculated density is off by more
than 5%, repeat the experiment.)
