For this method to work the solid must (a) be more dense than the liquid, and (b) not react with nor dissolve in the liquid. Water will be a suitable solvent for determining the volume of metals in this lab. An irregular shaped piece of metal has a mass of 131.0 g. You put it into a 100 mL graduated cylinder containing 22 mL of water, and the water level rises to 68 mL. What is the density of metal in g/mL? g/mL Calculator Submit Question
Use calculator to solve the problems. Write your answer in the correct scientific notation with the correct number of sig fig. Enter numbers only, no units. Enter scientific notation as (number)E(exponent) for example: enter 2 x 104 as 2E-4 (note there are no spaces) (9.4 x 10° mm) (4.5 x 10° mm) =

An object floats in water if it less dense than water. In other words if the volume of the material weighs less than the same volume of water (for example a piece of plastic). An object sinks in water if it is more dense than water (for example a piece of steel). The same principle applies for objects surrounded by air. Objects that are less dense than air, i.e., weigh less than the same volume of air, will float upward. For example, a helium-filled balloon floats upward because the helium inside the balloon weighs less than the same volume of air, since helium molecules weigh less than the nitrogen and oxygen that make up most of our atmosphere. Objects that are more dense than air, like humans, sink to the bottom of the atmosphere. Suppose we put some air in a sealed, flexible container like a balloon. No air can enter or leave the container, but since the container is flexible, it can easily change its size or volume. At first, the air temperature, air number density, and air…
A 2.98 liter glass bottle is full of oil. Assume it contains 2.98 L of oil. The density of oil is 1.34 g/mL. The glass bottle itself has mass of 226 grams. What is the weight of bottle plus oil in pounds? This is similar to question 11 in 'some extra questions' in module. You need to write your answer in the box with two numbers 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 two past the decimal is not the correct sig figs. Nonetheless, you have to follow that direction.
