How do I find the density of water using the density of an empty graduated cylinder that weighs 86.246g and also using the mass of a graduated cylinder with 10 mL of water that weighs 95.980g

How do I find the density of ethanol using the density of an empty graduated cylinder that weighs 86.246g and also using the mass of a graduated cylinder with 10 mL of ethanol that weighs 93.945g

Specific gravity is defined as the density of a substance divided by the density of water. Determine the density of ethanol

Solutions

Expert Solution

A:- Equation for the calculation the dencity of the given liquid, dencity = mass / volume

      mass of the water = 95.980 - 86.246

                                    = 9.734 grams

     volume of water = 10 mL

Dencity of water = 9.734 g / 10 mL

                          = 0.9734 g / mL

Dencity of ethanol, mass of ethanol = 93.945 - 86.246

                                                          = 7.699 grams

                            volume of ethanol = 10 mL

               Dencity of ethanol = 7.699 g / 10 mL

                                             = 0.7699 g / mL

To identify a liquid substance, a student determined its density. Using a graduated cylinder, she measured out a 45-mL sample of the substance. She then measured the mass of the sample, finding that it weighed 38.5 g. She knew that the substance had to be either isopropyl alcohol (density 0.785 g/mL ) or toluene (density 0.866 g/mL ). An experiment requires 53.5 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a...

A graduated cylinder filled with water rests upside down in a container of water at 0 C. The water is 7.00 cm deep. Attached to the base of the cylinder is a small ring (but since the cylinder is upside down, the ring is at the highest elevation, available for grabbing). The base of the cylinder has mass 10.0 grams with ring included. The cylinder itself has radius 3.00 cm, height 40.0 cm, and mass 100.0 grams (including the base...

a) If 42.1 mL of 1.02 M sodium hydroxide, measured using a graduated cylinder, is placed in a beaker filled with 300 mL of DI water, what is the concentration of the diluted NaOH solution? b) Why does this calculation only provide an estimate of the NaOH concentration? In other words, why do we have to standardize the NaOH in this experiment to find its exact concentration? (Hint: think about the glassware
