11 lis 2021 · Use the three sets of mass and volume measurements to calculate three density values for water. Then take the average of these three density values. Finally, look up the true density of water at the temperature used, and evaluate the accuracy of your average density value by calculating your percent error.

23 kwi 2021 · While there are many ways to determine the density of an object, perhaps the most straightforward method involves separately finding the mass and volume of the object, and then dividing the mass of the sample by its volume.
3 dni temu · What you're probably looking for is the volume of a rectangular cuboid (or, in more common terms, you want to find the volume of a box), which is a 3-dimensional object. To find the volume of a box, simply multiply length, width, and height — and you're good to go!
13 gru 2020 · Calculating density uses the formula D = m ÷ v, where D means density, m means mass and v means volume. Find mass using a balance scale, and use water displacement to find the volume of irregular objects. Water displacement works because the amount of water displaced by an object submerged in water equals the volume of the object.
You can calculate density by dividing the mass of a substance by the volume. In a mass versus volume graph, mass is on the y-axis, and volume is on the x-axis.

16 sie 2023 · Find the mass of only the water by subtracting the mass of the empty graduated cylinder. Record the mass of 100 mL of water in the chart. Use the mass and volume of the water to calculate density. Record the density in g/cm 3 in the chart. Pour off water until you have 50 mL of water in the graduated cylinder.
