According to the University of Hawaii's answer: There are seven quintillion five quadrillion grains of sand on all the beaches of the world. That's a 75 with 17 ze…ros following! "75 with 17 zeros following" (7.5x10^18) is seven quintillion, five hundred quadrillion. But what's an extra 495 quadrillion with so many variables in the equation? Consider more possibilities... With oceans rising and the deserts expanding, the question of grains of sand on the beach is kind of arbitrary. I think we would do better to ponder a more global picture: an estimate of all "sand" particles on the entire earth's surface, (including that which is covered by salty, briny, or fresh seas and rivers). Of course "sand" varies by composition, but is defined by size of particle. Tough questions then arise regarding the unexplored ocean floor, which includes a lot of silt (the same composition, but different size per particle than sand). Perhaps we could correct for that based on volume of silt, (or gravel, for that matter), per grain of sand under the sea. With massive erosion occurring due to water runoff and flooding caused by widespread deforestation, the intractability of the problem becomes as troublesome as estimating the number of stars in the expanding universe. Isn't that the analogy that captures our imagination, anyway - stars versus grains of sand? But another answer is: The exact number is not known. The exact number can't be known to mere mortals. The number of grains of sand is constantly changing as rock is worn away daily into more sand and tons of sand are melted daily to make glass and other products. Then you come to the dilemma of deciding the point at which sand ground fine enough, when do you start to call it dust.
well if you added all the sand up in the world and counted them it would be at least 10000,000000,0000,0000,000,000 and more
Answer . In your sand sample, what is the average weight of a grain?
That will strongly depend on both the cross-sectional area of the regulating orifice, and the duration of the time period that the device is designed to delineate.
In scientific terms, a whole bunch of em.
This is an un-answerable question due to the fact that the number of grains of sand is constantly changing and we can not keep up with it. But I can tell you that Florid…a has more grains of sand than Rhode Island and less than the Sahara Desert. Hope I helped. Still counting.
the answer is 2000
If the sand is totally silicon dioxide and is assumed to be a uniform volume of one cubic millimeter then the number would be approximately 2*10^19 molecules, or 20,000,00…0,000,000,000,000
no one knows because no one can count all the sand in the world
7,008 grains= 1 pound of sand. Answer: The term "sand" can be assigned to wide range of particles. Studies indicate that mid-sized sands weigh 0.67 - 23 mg per grain. This me…ans there are from 1 500 000 to 43 000 grains per kg. A kg is 2.2 lb., so there are potentially 700 000 to 22 000 grains per pound.
There are 3 quarks in each neutron. There are 12 neutrons in each proton. There is 1 proton in each atom. There is 36 quarks in each atom. There are about 27 million atoms in …each grain of sand. 36 x 27,000,000 = 972,000,000. There are 972 million quarks in a grain of sand.
