Volume is the amount of space occupied by matter. ... The volume of a liquid can be directly measured with specialized glassware, typically in units of milliliters (mL) or liters (L) . In this lab, a beaker, two graduated cylinders and a burette will be used to measure liquid volumes, and their precision will be compared.
What lab instruments measure volume?
Chemists use beakers, flasks, burets and pipets to measure the volume of liquids.
How is volume measured?
Volume is the amount of space occupied by a sample of matter. The volume of a regular object can be calculated by multiplying its length by its width by its height . ... A milliliter is the volume of a cube that measures 1 cm on each side. Therefore, a milliliter is equal to a cubic centimeter (cm 3 ).
How is volume in science measured?
Volume, as measured in chemistry, is the amount of space that matter occupies. It is most often measured by the liter (L), 1.057 qt. in conventional units, or the milliliter (mL), 1/1000 of a liter, about 0.0338 of an ounce. It is often measured by cylinders, flasks, pipettes, or syringes in and out of the laboratory.
How do you measure a chemistry lab?
Measurement Lab (M-Lab), a fiscally sponsored project of Code for Science & Society, is a consortium of research, industry, and public interest partners focused on fostering, collecting, and publishing open Internet performance data .
What is volume formula?
Volume = l × w × h , where l is length, w is width and h is height. Sphere. Volume = 4/3 πr3 , where r is the radius. Cylinder. Volume = πr2h , where r is the radius and h is the height.
What are two examples that represent volume?
Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas. Common units used to express volume include liters, cubic meters, gallons, milliliters, teaspoons, and ounces , though many other units exist.
How do you find the volume of a human?
The average human has a mass of about 62 kg, or 62,000 grams. That means the average volume of a human is 62,000 cubic centimeters. To get the total volume of the human race, just multiply that by 7.6 billion : 470 trillion cc.
What is the most accurate tool to measure volume?
Volumetric flasks, burettes, and pipettes made for measuring small amounts of liquid are the most accurate, with tolerances of less than ±0.02. Research and testing require precise measurements, and many lab vessels are even designed to account for the liquid residue that clings inside a flask.
How do you measure in chemistry?
Chemists measure the properties of matter and express these measurements as quantities . A quantity is an amount of something and consists of a number and a unit. The number tells us how many (or how much), and the unit tells us what the scale of measurement is.
How do you calculate volume of a solid?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height .
How do you calculate capacity?
- They are calculated by means of the following formula:
- Human capacity = actual working hours x attendance rate x direct labor rate x equivalent manpower.
How do you calculate volume in Litres?
The first thing you need to do is multiply the length by the width by the height. That gives the number of cubic millimetres. To calculate the number of litres, you then divide that number by a million .
