What volume of a pure liquid (density 0.710 g/mL) has a mass of 0.290 kg? A) 4.08 ´ 102 mL B) 2.45 ´ 10–3 mL C) 2.06 ´ 10–1 mL D) 2.45 mL E) 4.08 ´ 10–1 mL
Suppose you have 150. mL of a substance with a density of 42.0 g/dm and want to determine the mass of the substance. The calculation can be broken down into three steps. First, convert the volume from milliliters to liters. Then, convert the volume from liters to cubic decimeters. Finally, determine the mass of the sample in grams. Show the unit analysis by placing the correct components into the unit-factor slots. The question marks (?) represent the answer to the...
Density is essentially a conversion factor for a substance allowing you to convert a mass of a substance to its volume or the volume of a substance to its mass. What would be the volume of 22.1 g of a substance (@ 250C) that has a density of 3.51 g/mL? (Report your answer with the correct number of significant digits)
The density of gold is 19.30 g/mL. A gold nugget has a volume of 25.65 mL. What is the mass of the gold nugget in dg?
25. The density of copper is about 8.96 g/mL. This means that a certain mass of copper will: a) Occupy the same volume as the same mass of water b Occupy a volume 8.96 times larger than the volume occupied by the same mass of water c) Occupy a volume that is 8.96 times smaller than the volume occupied by the same mass of water d) Always occupy a volume of 8.96 ml 26. 164.0 g of a substance occupy...
One particular solution is 74.5% by mass of a substance A. The density of the solution is 1.37 g/mL. A reaction requires 5.23g of A. What volume of solution is required?
An unknown substance has a mass of 43.3g and occupies a volume of 34.0 mL. What is it's density in g/mL
Density is equal to the mass of a substance divided by its volume: density = mass of substance/volume of substance Water displacement can be used to find the volume of a solid by placing the object in a known volume of water. When the object is added to water, the measured total volume increases. This final volume is equal to the volume of the initial water plus the volume of the solid object added. To determine the volume of the...
If you combine 350.0 mL of water at 25.00 degrees Celcius and 130.0 mL of water at 95.00 degrees Celcius, what is the final temperature of the mixture? Use 1.00 g/mL as the density of water.
Q1: Substance A has a density of 3 g/cm3 and substance B has a density of 4 g//cm3. In order to obtain equal masses of these two substances, what must be the ratio of the volume of A to the volume of B?
