How many meters tall is a student whose height is 54.2 inches? Round your answer to the nearest tenth. Question 2 The width of a human hair is 0.065 mm. Convert this quantity to micrometers. Enter a number in standard notation. Question 3 It is common lore that "vodka does not freeze". This is perhaps only true in a conventional freezer. 80-proof vodka will freeze around -16°F. Convert this temperature to Celsius. Round your answer to the nearest hundreth place.

Question 4 A student would like to calculate the density of a metallic solid. The solid was massed on a top-loading balanced and was found to have a mass of 36.49 grams. The solid was placed in a partially filled 50-mL graduated cylinder and displaced 4.6 mL. Calculate the density of the solid. Enter a number without units. Density = mass/volume T A O

> D D Question 10 Match the term to its definition. You may need to look up these terms. Physical properties Chemical properties Scientific Models Solution Element Question 11 O 19 mL O 19.17 ml O 19.6666667 mL The density of iron is 7.2 g/mL. How much volume would a 138 g piece of iron occupy? Density = mass/volume. O 19.2 mL [Choose ] [Choose ] compound Properties of matter that demonstrate its ability to change in composition Question 12 heterogeneous mixture Explanations for observed behavior in nature. A pure substance consisting of only one kind of atom in the form of homoatomic molecules or atoms Homogenous mixtures of two or more pure substances Properties of matter that can be observed or measured without changing the composition being studied [Choose ] [Choose ] The water level of a graduated cylinder is initially at 14.08mL. After placing a metallic necklace into the cylinder, the water level rises to 21.4mL. Provided that the density of the necklace's material is 9.894 g/mL, calculate the weight of the necklace in ounces. A pound is defined as 16 ounces. Hint: solve for the mass in grams, then convert your answer to ounces.
