Which is the correct formula to calculate density?
To calculate density, you divide the mass by the volume: Density = Mass ÷ Volume. Density is often written in mathematics as the symbol p or D. Mass can be written as m, and volume can be written as V. So if you want to be fancy, the formula looks like this:
Do you have to report volume in density calculation?
The significant figures reported in the density calculation are those of your least precise measurement. So, if your mass is 22 kg, reporting a volume measurement to the nearest microliter is unnecessary. Another important concept to keep in mind is whether your answer makes sense.
How to calculate the density of a sugar cube?
density = mass/volume. density = 11.2 grams/8 cm3. density = 1.4 grams/cm3. Answer 1: The sugar cube has a density of 1.4 grams/cm3. Question 2: A solution of water and salt contains 25 grams of salt in 250 mL of water.
How to calculate the density of a rock?
Problem 1: You have a rock with a volume of 15cm 3 and a mass of 45 g. What is its density? Density is mass divided by volume, so that the density is 45 g divided by 15cm 3, which is 3.0 g/cm 3. Problem 2: You have a different rock with a volume of 30cm 3 and a mass of 60g.
Which is the Greek letter for density density?
Most noteworthy, the symbol ρ is mostly made use of for expressing this measurement. Furthermore, this symbol happens to be the lower case Greek letter rho. Some individuals also make use of the letter D for expressing this measurement.
Which is the joint probability density function Satis?
Joint Probability Density Function A joint probability density function for the continuous random variable X and Y, de- noted as fXY(x;y), satis es the following properties: 1. fXY(x;y) for all x, y 2. 1 1 fXY(x;y) dxdy= 1 3. fXY(x;y) dxdy For when the r.v.’s are continuous.
