Grains of fine California beach sand are approximately spheres with an average radius of 45 µm and are made of silicon dioxide. A solid cube of silicon dioxide with a volume of 1.00 m3 has a mass of 2600 kg. What mass of sand grains would have a total surface area (the total area of all the individual spheres) equal to the surface area of a cube 1.50 m on an edge?
answer is in kg
To convert mass units, you will need to use a conversion factor. This is a number that relates the two units you are trying to convert. Simply multiply the original measurement by the conversion factor to get the new measurement. For example, to convert kilograms to pounds, you would multiply the number of kilograms by 2.20462.
The most common mass units used in conversions are grams, kilograms, ounces, and pounds. These units are commonly used in everyday life and in scientific measurements.
To convert between metric and imperial mass units, you will need to use conversion factors. For example, to convert kilograms to pounds, you would multiply the number of kilograms by 2.20462. To convert pounds to kilograms, you would divide the number of pounds by 2.20462.
To convert between different units within the metric system, you will need to use the prefixes for each unit. For example, to convert from grams to kilograms, you would divide the number of grams by 1000. To convert from milligrams to grams, you would divide the number of milligrams by 1000.
The best way to keep track of conversions with mass involved is to write down each step of the conversion and make sure your units cancel out correctly. This will help ensure that you are converting the measurement accurately. Additionally, you can use online conversion calculators or conversion charts to double check your work.
