A general chemistry student found a chunk of metal in the basement of a friend's house.To figure out what it was,she used the ideas just developed in class about density. She measured the mass of the metal to be 111.2 grams.Then she dropped the metal into a measuring cup and found that it displaced 15.2mL of water. Calculate the density of the metal. Density=     G/mL

A student wishes to determine the density of a solution of lithium hydroxide. He finds the mass of the flask to be 27.532 g. When he fills the flask with water at 22℃ (d= 1.00 g/mL), its mass is 37.441 g. He finds that the mass of the flask filled with lithium hydroxide solution is 38.138 g. What is the density of the lithium hydroxide solution?

a student has been given a solid sample and asked to calculate its density. She measured the mass of the solid sample and recorded it on her data sheet as 4.528g. She recorded the initial volume as 4.7 mL and final volume as 6.2 mL. What is the density of the sample

A pycnometer is a glass apparatus used for accurately determining the density of a liquid. When dry and empty, a certain pycnometer had a mass of 27.234 g. When filled with distilled water at 25.0°C, it weighed 36.491 g. When filled with chloroform (a liquid once used as an anesthetic before its toxic properties were known), the apparatus weighed 40.946 g. At 25.0°C, the density of water is 0.99704 g/mL (a) What is the volume of the pycnometer? i mL (b) What is the density of chloroform? i ! g/mL eTextbook and Media Attempts: 2 of 15 used Submit Answer Save for Later 山T 19 MacBook Air DII DD 吕0 888 F8 F10 F5 F6 F7 F3 F4 F1 F2 #3 $ % & 2 3 5 7 8.

A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, she used the ideas just developed in class about density. First she measured the mass of the metal to be 198.1 grams. Then she dropped the metal into a measuring cup and found that it displaced 17.3 mL of water. Calculate the density of the metal.

The density of methanol, a colorless organic liquid used as solvent, is 0.7918 g/mL. Calculate the mass of 89.9 mL of the liquid.

Bud N. Chemist must determine the density of a mineral sample. His four trials yield densities of 5.27 g/cm3, 5.28 g/cm3, 5.27 g/cm3, and 5.29 g/cm3. Bud's calculated average density was 5.28 g/cm3. Independent studies found the correct density to be 4.75 g/cm3. Which of the following statements represents the best analysis of the data?     Bud's results have much greater accuracy than precision   Bud's results have low accuracy and low precision   Bud's results have high accuracy and high precision   Bud's results have much greater precision than accuracy
