Experimental: 1) Write the names of laboratory equipments.(10pts) 2) Fill in the blanks with suitable words.(20pts) - A/An property is independent of the quantity of material measured since it is the ratio of the mass of an object to its volume. ( ullet ) refers to how closely a measured value agrees with each other, whereas .indicates how close the measurement is to the true value. - The ratio of mass to volume is defined as Calculation a) A student weighes an empty beaker as ( 25.4108 mathrm{~g} ). He/she measures ( 15.00 mathrm{~mL} ) of distilled water with a pipette and empties the pipette into the same beaker. Then weighes the beaker with distilled water. He/she performs the same procedure twice and measures the weight of beaker + distilled water each time. The collected data ( 40.1425 mathrm{~g}, 39.9987 mathrm{~g}, 40.0213 mathrm{~g} ). Calculate relative average deviation for density values that you calculated. Are the results precise? (20pts) b) The student, this time, performs the same procedure by measuring ( 15.00 mathrm{~mL} ) of the distilled water with a pipette, a graduated cylinder and a beaker, then uses the same beaker used in part A (mass ( =25.4108 mathrm{~g} ) ) for mass measurements. Collected data is ( 41.0412 mathrm{~g} ) for pipette, ( 43.9971 mathrm{~g} ) for graduated cylinder and ( 45.0345 mathrm{~g} ) for beaker. Calculate the of volume of water for each equipment? In which of the measurements, the student has the most accurate measurement of volume? ( left(d_{ ext {water }}=0.997 mathrm{~g} / mathrm{mL} ight)(20 mathrm{pts}) ) lusion: (20pts) What might be the possible errors that might have occurred during the experiment? Can you prevent them?
