With respect to the rules of sig figs explained in the first image, is 8.96 g/cm3 the correct answer or would it need to be two sig figs instead? 4. Consider the tabulated data collected by a student for an unknown metal sample. Use this data to calculate thedensity of the metal (in g/cm³). Show your work clearly. Density of a compound is given by:Mass of compound (in g)Density =Mass of Empty BeakerMass of Beaker and Metal sampleInitial volume of water in cylinderFinal volume of water and Metal sample44.656 g124.400 g12.7 mL21.6 mLVolume of compound (in cm^3 or mL)79.744 g8.9 cm^3Density of metal sample=Mass of sample = Mass of beaker & metal sample - mass of empty beaker124.400 g -44.656 g = 79.744 gVolume of sample = Final volume of metal & water sample - initial volume of water in cylinder21.6 mL 12.7 mL = 8.9 mL or cm^3= 8.96 g/cm^3 Since measurements are often used in calculations to obtain other values of interest, it is important toconsider the number of significant figures that should be recorded for the results of such calculations. Ifmultiplying or dividing measured values, the result should be reported with the lowest number ofsignificant figures used in the calculation. If adding or subtracting measured values, the result should bereported with the lowest number of decimal places used in the calculation.

Significant figures are those important digits which measures the accuracy of calculation.

A solution made by dissolving sugar in water is homogeneous because the composition is the same everywhere. But if you could look with very high magnification, you would see locations with water particles and other locations with particles of sugar. How can we say that a sugar solution is homogenous?
The mass of a beaker is 5.333 g. After 5.00 mL of a concentated hydrochloric acid solution is pipet Ted into the beaker, the combined mass of the beaker and the hydrochloric acid sample is 11.229 g. From the data, what is the measured density of the hydrochloric acid solution?

A student places 14.8 mL of water in a graduated cylinder. The mass of the water and the graduated cylinder is found to be 41.721 grams, and then the balance is tared. After adding a number of metal pellets to the graduated cylinder, the liquid level in the cylinder is now 28.8 mL. The cylinder with the water and metal pellets is placed back on the balance, and the measured mass is 71.371 grams. Calculate the density of the metal pellets in g/mL. Do not include units in your answer.
