What is the weight of a grain of sand?
approximately 0.011 grams
How do you write 0.0044 in scientific notation?
4.4 × 10-3 m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| How big is a grain of sand?
By another definition, in terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm (or 1⁄16 mm) to 2 mm. An individual particle in this range size is termed a sand grain.
How many micrograms is a grain of sand?
50 micrograms
How do you measure the mass of sand?
To calculate the weight of sand, you need to determine the volume of each mineral in the sand, multiply the volume by the mass density. Then you can multiply the masses of each component mineral by the local acceleration of gravity, to determine the weight of the sand.
How many milligrams is a grain of sand?

mass = 6.66 × 10−4 g → 0.67 mg
How many micrograms is a grain of salt?
60 micrograms
What is the weight of 1 m3 of sand?
1,600 kilograms 1.6 tonnes
How do I write a number in scientific notation?
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
How many grains of sand are in a pound of sand?
41,235 grains
How big is a grain of sand in inches?
Sand—rock fragments or mineral particles that range in diameter from about 1/16 to 2 mm (from 0.002 to 0.08 inches).
