Lead is an elementary substance that occurs as a malleable metal with a density of 11.4 g/mL at ambient temperature and pressure. Lead metal can be extracted from a mineral called galena, which contains 86.6%% lead by mass. A particular ore contains 68.5% galena by mass If the lead can be extracted with 92.5%% efficiency, what mass of ore is required to make a lead sphere with a 7.00 cm radius? Express your answer with the appropriate units.
A student decided to undertake a balance calibration exercise during a lab session involving burette calibration. He found the apparent weight of calcium carbonate in air to be 100 grams and density to be 1.33g/mL. Assume that the standard steel weight used in the calibration has a density of 8.0g/mL and air has a density of 0.0012g/mL. What would be the true mass of the calcium carbonate sample?
1.) A dense plastic-like shape has a mass of 42.985 g and has a volume of 41.96 mL. What is the density of the substance? 2.) Another plastic-like piece has a mass of 65.389 grams and displaces 53.652 grams of water (measured at 24.6 ⁰C). Is this piece likely to be composed of the same material as the sample in problem 1? Explain using the Claim-Evidence-Reasoning process.
1000 mg of granular salt is briefly stirred into a glass container of 1/4 liter volume filled with water. After briefly mixing, some salt is still seen at the bottom of the glass. The undissolved salt is filtered from the water, weighed and determined to have a mass of 200 mg. What is the dissolved phase concentration of salt remaining in the water? Provide your answer to the nearest whole number in units of mg/l. Example: 120 (no decimals, commas, or zeros after decimal)
In the UV assay of paracetamol you are required to weigh tablet powder “…containing 0.150 g of Paracetamol…”. If the stated content of paracetamol per tablet is 500 mg and the weight of 20 tablets is 11.223 g then the amount of paracetamol tablet powder to be weighed is
A 76.00 pound flat of mercury $156.50. The density of margarie is 13.534g/cm3. Find the price of 1cubic inch of mercury by calculating intermediate values
A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of ethanolamine, pentane, chloroform, acetone, and glycerol. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: Next, the chemist measures the volume of the unknown liquid as 1049. cm and the mass of the unknown liquid as 1.07 kg.
A density bottle test on a sample of dry soil gave the following results:Mass of 50ml density bottle empty (g) = 25.07Mass of 50ml density bottle+20g of dry soil particles (g) = 45.07Mass of 50ml density bottle+20g of dry soil particles, with remainder of space in bottle filled with water (g) = 87.55Mass of 50ml density bottle filled with water only (g) = 75.10Calculate the relative density (specific gravity) of the soil particles. Round your answer to 2 decimal places.

A 795-centigram sample of borax was placed in a certain volume of water at 25 °C. After adding the sample, the graduated cylinder was read at 35 milliliters, where a rise of 2.7 milliliters was observed. What is the weight of the sample in grams? What is the initial volume of water in millimeters? What will be the weight of displaced water in grams? What is the specific gravity of the solid? What is the specific volume?
The mass of a beaker is 8.342 grams. After 3.00 mL of an organic liquid is pipetted into the beaker, the combined mass of the beaker and the organic liquid is 10.697 grams. From the data, what is the measured density of the organic liquid ?
Hemant Kohli please answer: A sample of 500 g dry sand, when poured into a 2 litre capacity cylinder which is partially filled with water, displaces 188 cm3 of water. The density of water is 1gm/cm3 . The specific gravity of the sand is (a) 2.55 (b) 2.72 (c) 2.66 (d) 2.52
