How do you find mass of a rock by its density?
Determine its volume by how much water it displaces, then divide mass by volume
How could you find out the volume of metal in a teaspoon?
Fill a graduated container with enough water to completely submerge the spoon.Record the water level.Submerge the spoon in the water.Record the water level again.Subtract the 1st water level from the 2nd water level; the difference is the volume of the spoon.
How do you find the volume of bottle?
A label on a bottle bought in a shop would show the volume. If there is no label, fill the bottle with water to the top, then empty the water into a measuring jar or cylinder. The volume is then read off the scale marked on the measuring jar or cylinder.
How do i calculate the Volume of water a cylinder shaped vessel will hold?
To find the Volume: (1) find the flat area (A = Pi*R²), (2) multiply the Area by the Depth/Height (V = AD). To find how much water the vessel will hold: water = 231 cu inches per gallon, or 7.481 gal per cu ft.
How do you find the volume of a pear?
The Easiest way- fil a marked measuring cup with enough water to cover the pear. Note the measurement. now push the pear into the water. Note the larger measurement. Subtract smaller from larger. Difference is the volume of water the pear displaced, which is equal to the volume of the pear.
A pipet delievers 9.98g of water at 20 degrees celsius What volume does the pipet deliver?
To calculate the volume of water delivered by the pipette, you need to convert the mass of water to moles using its molar mass (18 g/mol). Then, you can use the density of water (1 g/mL) at 20 degrees Celsius to convert moles to volume. The volume delivered by the pipette would be approximately 9.98 mL.
Suppose that after delivery several drops of the water cling to the inner wall of the pipet because the pipet wall is dirty How does this technique error affect the reported density of the solid?
If water drops cling to the inner wall of the pipet, the volume of water dispensed will be less than the true value, leading to a lower reported density for the solid. This is because the volume of water measured would be underestimated, causing a decrease in the calculated density of the solid.
A student determined the volume of water from a pipet by the method described in Part B The volume determined on a mass basis was consistently greater than 10.00 mL what would acc?
If the volume of water determined on a mass basis using the pipet is consistently greater than 10.00 mL, it suggests that there may be a systematic error in the measurement technique or calibration of the pipet. The student should recalibrate the pipet to ensure accurate volumetric measurements, and also consider factors such as temperature, meniscus reading, and technique when measuring volumes.
How do you calibrate a pipet?
A pipet is calibrated by pouring a liquid of known volume into it and taking the reading in order to determine by how much it might be deviating. This technique is regarded as a quantitative method.
Can a pipet be placed in a reagent bottle?
Yes, a pipet can be placed in a reagent bottle to withdraw specific volumes of the reagent as needed. It is important to ensure that the pipet tip does not touch the sides or bottom of the bottle to prevent contamination and maintain accuracy in volume measurement.
What do you use to measure a milliter?
A millilitre is a volume of 1 cm3. You can measure this quantity of volume by a measuring tube, burette or pipet tube.
When using a pipet can you state the volume of the aliquot without calculating it?
Yes, the volume of the aliquot is typically indicated on the pipette itself. Most pipettes have volume markings along the side that allow you to easily set and dispense the desired volume without needing to calculate it.
How do you clean your pipet?
Fill a mug or a container with warm tap water. You are using warm tap water because, tap water contains microorganisms which will help flush out the chemicals and it is warm ,because warm water can cleanly stabilize your pipet so it is ready for it's next use. Pinch your pipet inside the water so it fills up to about 15-20 milliliters. Squirt in in the sink. Do the same thing for a few times. Atleast 5 times. Now your pipet is clean and ready for its next use.Why is it important to clean your pipet? It can contain chemicals from your previous experiment which will give inaccurate or wrong results and data.
How do you find the volume of an irregular piece of cork which floats on water?
You can find the volume of the irregular cork by immersing it in a known volume of water and measuring the amount the water level rises. The volume of water displaced is equal to the volume of the cork.
Can water displacement find the volume of substances?
Yes, water displacement can be used to find the volume of solid objects that do not dissolve in water. By measuring the change in water level before and after submerging the object, you can calculate its volume based on the amount of water displaced.
What measurements must you make to find density of a sample of matter?
density = mass / volume. so you need to weigh to find the mass. To find the volume submerse in water and record the displacement of water to find the volume.
How do you find volume of a bottle when its mass is given it's weight with the water is given and the waters density is given?
To find the volume of the bottle, you need to subtract the weight of the water from the total weight of the bottle and water. Then, divide this difference by the density of water to find the volume displaced by the water and consequently the volume of the bottle.
