What is the mass for 20cm3 volume?
To determine mass, you also need the density of the substance. Mass = volume x density. Without the density, we cannot calculate the mass.
If you have a mass of 80grams and a volume of 20cubic centimetres what is the density?
The density is calculated by dividing the mass by the volume. In this case, the density would be 80g / 20cm^3 = 4 g/cm^3.
Why must a metal sample always be dry before its mass or volume is taken?
A wet metal sample can have water molecules attached to its surface, which can affect its mass and volume measurements. Removing water ensures accurate data and prevents errors in calculations.
A sample has a mass of 35.4 g and a volume of 36.82 mL What is the density of the sample?
The density of the sample can be calculated by dividing the mass of the sample (35.4g) by its volume (36.82 mL). Density = Mass/Volume Density = 35.4g / 36.82 mL Density = 0.962 g/mL
A saturated soil sample has a mass of 1.38kg and a volume of 0.6 liters. After dried in a oven for 24 hours the mass of th soil sample is 1.13kg. calculate mass of water?
Initial water content in the soil sample can be calculated using the initial mass and final mass after drying. Initial water content = (Initial mass - Final mass) = 1.38 kg - 1.13 kg = 0.25 kg. This is the mass of water in the soil sample.
