Get an original essay To measure the density of wood you need to find out the mass and volume of the wood. This is because density equals mass divided by volume. First you start by calculating the volume of the wood, this is done by multiplying the length of the wood, the width of the wood and the height of the wood together. Once you find out the volume of the wood using the formula, you need to calculate the mass of the wood using a digital scale as it gives you the exact value of the wood in grams. Now that you have the mass and volume of the wood you need to find out the density using the calculated mass and volume. This is done by dividing the mass by the volume to find out the density of the wood you are trying to calculate (b) Explore another method of measuring the density of the solid and compare it to the method described above in (a) Another way which can find to determine the density of a solid object is using a pycnometer. This will allow you to find out the value of any solid object. To calculate the density of the object using a pycnometer we must first find out how much the mass of the pycnometer is. Once this is done, you then need to measure the pycnometer with the solid object inside it. Once this is done, we need to add water and determine the weight of the pycnometer. From the water added to the pycnometer we can then obtain the volume of water added using the formula V= m/ρ. The volume of the object will therefore allow us to find the difference between the volume of water that fills the empty pycnometer. The volume will then be calculated as the mass of the object subtracted from the mass of the water and then divided by the density of the water. Once we calculate this, we can use the formula density equals mass divided by volume. This is another way you can find the density of water. However, the two methods are different. The first process allows you to find the density more quickly than using a pycnometer. However, it is not precise due to the different scales that can be used to measure mass. However, the pycnometer provides more reliable results when determining density. Also, the pycnometer is a longer process to complete to determine the density.(c) Briefly describe the method of measuring the density of water. To calculate the density of water you need to determine a volume of water using a graduated cylinder, this cylinder is calibrated in milliliters. The units for this are 1 ml is 1 cm3. Since we will be measuring the mass of the water in the cylinder, we need to subtract the mass of the cylinder from the total mass of the water and the cylinder. Using a digital scale will allow you to make it easier. You must first place the empty cylinder on the scale. Then, once you calculate the mass, you subtract it from the volume of water you measure using the cylinder. So, once you calculate the mass of the water and the volume of the water, you need to divide the mass of the water by the volume of the water to get the total density of the water.

The first thing is first you have the pycnometer and you fill it with water, this will give you the volume of water that is in the pycnometer. However, we need to measure the density of water, the formula for water is V= mH2O / ρH2O. So long as.
