A brick of a certain metal has area on top of 3.54 cm x 6.93 cm. It has mass 921 g. How high is the brick in cm? The metal has density of 10.6 g/cm3 2.54 cm 1 inch Ixhxw V V= m/d You need to combine the above equations; this is a typical math skill you need in chemistry. You need to write your answer in the box with one number past the decimal. Please don't worry about the sig figs in this case--in these formula problems, the Canvas software will give a variety of questions and each student gets their data with different sig figs. So I just have to choose and sometimes it might seem that one past the decimal is not the correct sig figs. Nonetheless, you have to follow that direction. For the same reason, your brick may seem to be odd shaped-- please don't worry about t.

One of the ionic compounds in sports drinks is potassium dihydrogen phosphate (KH2PO4). The label on one of these drinks states that 275 mL of the solution contains 31.625 mg of potassium. KH2PO4 is the only ingredient in the solution that can provide this potassium. How many grams of KH2PO4 are dissolved in the drink solution to provide the required mass of potassium shown? Express your answer rounded to 3 decimal places.
A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, he tried the following experiment. First he measured the mass of the metal to be 177.5 grams. Then he dropped the metal iñto a measuring cup and found that it displaced 15.5 mL of water. Calculate the density of the metal. Density = g/mL Use the table below to decide the identity of the metal. This metal is most likely Densities of Some Common Substances Substance Density (g/mL) Water 1.00 Aluminum 2.72 Chromium 7.25 Nickel 8.91 Copper 8.94 Silver 10.50 Lead 11.34 Mercury 13.60

Round to the proper number of significant figures. v=_____in3
If a sample of gold alloy has a mass of 87.7 g and is 78.3% gold by mass, what percentage of the alloy is made up of other metals? Write your answer to the nearest tenth of a percent. (I had to alter the wording of this question since it wasn't calculating significant figures properly, so if you got it wrong because of significant figures you can assume you probably actually got it correct.)
In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun, but occupying less space than our moon. Suppose that one of these black holes has a mass of 8×103 suns and a radius equal to one-half the radius of our moon. What is its density in grams per cubic centimeter? The mass of the sun is 2.0×1030kg and the radius of the moon is 2.16×103mi. (Volume of a sphere =43πr3.)
