Part C Iron has a density of 7.86 g/cm (1 cm = 1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 4.25 kg . Note that the density is provided in different units of volume and mass than the desired units of volume (dL) and the given units of mass (kg). You will need to express the density in kg/dL (1 cm = 1 mL) before calculating the volume for the piece of...
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...
4) what volume (mL) of a 3.1% (by mass) chlorine solution (density= 1.15 g/mL) contains enough chlorine to raise the chlorine concentration of a 27000 gal swimming pool to 2.5 ppm (by mass). Assume a density of 1.00 g/mL for the pool water. (4 pts)
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
(a) What is the density in units of g/mL ofa liquid with a mass of40.75 μg that occupies a volume of292 x 10-8 L? (b) Determine the mass in kg of 6.3 x 10 nL of the liquid.
You will be using 25.00 mL of 3.00% by mass solution ({mass H2O2/mass solution}*100) of hydrogen peroxide. Assume the density of this solution is 1.000 g/mL. If all of hydrogen peroxide decomposes to water and oxygen according to the reaction 2H2O2(aq) ↔2H2O(l) +O2(g) what is the total volume of oxygen gas generated if the temperature is 27° C and the pressure is 775 Torr (ignore the effects of water vapor present)? 760 Torr = 1 atm R = 0.08206 L•atm/K•mol...
An object has a mass of 100 kg and a density of 10 g/cm3. What is the volume of the object in cm3? (Hint: Watch Session 13/Lecture/Video Lessons on Matter/Density)
1. You add 9.1 g of iron to 29.30 mL of water and observe that the volume of iron and water together is 30.46 mL . Calculate the density of iron. Express your answer to two significant figures with the appropriate units. 2. Since density depends on the mass and volume of an object, we need both of these values combined in the correct way to solve for density. Keep in mind that we may not be given the mass...
