A metal object of an irregular shape has a mass of 31.5 grams. When the metal is added to
water in a graduated cylinder, the volume of water increases from 5.28 mL to 7.61 mL.
(A) How much water does the metal displace?
(B) Calculate the density of the metal.
(C) Is the metal made of platinum? Explain.
(Hint: the density of platinum = 21.4 g/cm³)
A group of students took turns using a laboratory balanceto weigh the water contained in a beaker. The results theyreported were 111.42 g, 111.67 g, 111.21 g, 135.64 g,111.02 g, 111.29 g, and 111.42 g.(a) Should any of the data be excluded before the average is calculated?(b) From the remaining measurements, calculate the average value of the mass of the water in the beaker.(c) Calculate the standard deviation s and, from it, the 95% confidence limit.
You are given a hammer, a battery, a bulb, wires and switch.(a) How could you use them to distinguish between samples of metals and non- metals?(b) Asses the usefulness of these tests in distinguishing between metals and non-metals?
