In mathematics, we can make conversions between different units of measurement using conversion facts. Conversion facts are relationships between two different units stating how much of one unit is contained in the other unit, and we use them by converting the amount we have of one unit to an ...
What is the mass, in grams, of 1.24 mol of water? What does a liter of water weigh? The mass of an empty graduated cylinder is 72.57 g, the volume of water is 50.00 mL, the mass of graduated cylinder and water is 122.38 g. What is the mass of the water? What is the density ...

How to calculate the weight of a certain amount of water at room temperature? How much ice in grams would have to melt to lower the temperature of 352 mL of water from 25 degrees C to 0 degrees C? (Assume that the density of water is 1.0 g/mL.) ...
Depending on temperature, air can hold a fixed amount of water vapor; relative humidity is the ratio of actual vapor in the air to this fixed amount. For example, at a temperature of 68 degrees Fahrenheit (20 degrees Celsius), one cubic meter (35 cubic feet) of air can hold about 18 ...
So if you had a different, irregular piece of aluminum that weighed 550g and displaced 204mL of water in a graduated cylinder, then your equation would be ρ = 550g/204mL = 2.7g/mL. If the substance you're trying to find the density of is a liquid, you can simply pour the liquid...

At 6 grams of total carbs per two-tablespoon serving, flaxseeds may appear to be high in carbs, but most of those carbs come from fiber, which you can subtract from your total carb count to get your “net” carbs. In fact, the fiber content in flaxseed is one of its most well-kno...
