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...
Ethylene glycol (antifreeze) has a density of 1.11 g/m Cm^3, What is the mass in grams of 361 mL of ethylene glycol? Express your answer with the appropriate units. What is the volume in liters of 3.60 kg of ethylene glycol? Express your answer with the appropriate units.
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...

How do I convert Extinction coefficients of (48853 M^-1 cm^-1) to (mg/ml)^-1 cm^-1 or (ml/mg)*cm^-1
Concentrations of solute in solvent, whether in saturated solutions or not, can be expressed in many ways (molarity, molality, ppm, percent by mass, etc.). Molarity = moles of solute / liter of solution molality = moles of solute / kg of solvent ppm = mg solute / liter of solution ppb = microgram of solute / liter of solution %-by-mass = (grams of solute / grams of solution) x 100% To convert from %-by-mass to Molarity, assume 100g of solution,...
