What is the density of a 8 cm3 block of brown sugar?
Explanation: The density will be mass divided by volume, which in this case is 12/8 or 1.5 g/ cm3 . However, if the block is comprised of compressed granules of sugar, then this figure is the bulk density, not the volumetric mass density.
What is the percent error of the students calculated density?
Step 1: Subtract the accepted value from the experimental value. Step 3: Divide that answer by the accepted value. Step 4: Multiply that answer by 100 and add the \% symbol to express the answer as a percentage. The percent error of your density calculation is 2\%.
How do you find the density of an object?
The formula for density is the mass of an object divided by its volume. In equation form, that’s d = m/v , where d is the density, m is the mass and v is the volume of the object. The standard units are kg/m³.
What is the density of the corn oil if its volume is 114 cm3?
The density of the corn oil is 0.926 g/cm3 .
How do you find the mass with density and volume?
Divide the mass by the density of the substance to determine the volume (mass/density = volume). Remember to keep the units of measure consistent. For example, if the density is given in grams per cubic centimeter, then measure the mass in grams and give the volume in cubic centimeters.
What is the density of 2700g?
Aluminium has a density of 2700 ( kg)/m^3.
How do we calculate percentage error?
To calculate percentage error, you subtract the actual number from the estimated number to find the error. Then, you divide the error in absolute value by the actual number in absolute value. This gives you the error in a decimal format. From there, you can multiply by 100\% to find the percentage error.
What is the formula for calculating percent error?
Formula. The formula is: PE = (|accepted value – experimental value| \ accepted value) x 100\%.
How can you measure density?
Using a vernier caliper or ruler, measure the length, depth and width of the object in centimeters. Multiply these three measurements to find the volume in cubic centimeters. Divide the object’s mass by its volume to determine its density. Density is expressed in grams per cubic centimeter or grams per milliliter.
What is the density of corn oil G cm3?
0.91 to 0.93 g/cm3
The density of the oils varies with each type and temperature. The range is from 0.91 to 0.93 g/cm3 between the temperatures of 15 °C and 25 °C….Density of Cooking Oil.
| Name | corn (maize) |
|---|---|
| Specific Gravity @ 15.5 °C | 0.9213-0.9250 |
| Name | rapeseed |
| Specific Gravity @ 15.5 °C | 0.9133-0.9168 |
What is the mass of corn oil?
In your case, the density of corn oil is said to be equal to 0.92 g mL−1 . The volume is expressed in milliliters, mL , which means that one unit of volume will be equal to 1 mL . This means that for every 1 mL of corn oil that you have, you also have a mass of 0.92 g .
