A mole equals 6.022415×1023 so the line of sand would be 6.022415×1023 mm long.
This is equal to 6.022415×1018 km or 3.7419852437x1018 miles (3.742 exa miles or 3.742 quintillion miles).
In it's full form this is three quintillion, seven hundred and forty one quadrillion, nine hundred and eighty five trillion, two hundred and forty three billion, seven hundred million miles, or a very long way indeed.
To put that figure into context, the distance from the Earth to the sun is 92.960 x106 miles (ninety two million miles) so the line of sand would be roughly 40 billion times longer than that distance.
The diameter of our galaxy is approximately 100,000 light years (5.874x1017 or five hundred and eighty seven quadrillion, four hundred trillion miles), so the line of sand would be around six times longer than that (636 ,976 light years to be precise).
To sum up, it would be a very, very, very, very long line of sand.

A grain is an old-fashioned, medieval unit of weight equal to the weight of a grain of wheat or barley, it isn't used in the modern world. One grain was roughly equivalent to 64.8 milligrams, so 7.5 would be 7.4 time 64.8, which is 486 milligrams, or 0.486 grams.
Measure a bunch of them, count them, and divide the weight by the number of grains.
Pumice normally doesn't have any grains at all. It would be very unusual for it to have grains. Just like Obsidian, Pumice is cooled too fast to have any grains in it. One of the biggest differences between them is that Pumice is cooled with pockets of air while Obsidian has a glassy look.
Using 238,900 miles as the distance to the moon the trip would take you about five months at 65 miles per hour. Now, imagine trying to reach the sun at 65 mph; the trip would take about 163 years.
50 grains.
One pancake would be equal to one serving of grain.
wheat and vitamins
If a grain is about 60 mg, then 10 grains of cocaine would be about 600 mg or .6 grams, quite a decent amount for sure...

Static or sliding friction? In any event, wood has grain. I would guess that the friction with the grain is different from the friction against the grain. Hmm, different woods have different grains. What is the friction of a wood floor?
because moisture attrats fungus and bacteria as aresult grains destroyed
they would reach 1024830 miles because the distance around the earths equator is about 24,830 miles. 1000000+24830=1024830
An open answer to the desired increase in grain would include :- increase the number of crop cycles per year, increase the size of the individual grains, increase the number of grains per head of grain, increase the number of heads of grain per plant, increase the type of land on which grain could be grown, increase the climate range over which grain may be grown.In fact, folk are working on most of these.Even esoteric aims such as converting plant metabolism to C4 photosynthesis instead of C3, is being worked on.And the contributions of cross-breeding between grains is another fruitful area.
Wheat, corn, and soybean, (technically corn and soybeans are not grains so rice and oats would be next).
It depends on Long, LR, Extra Long, etc. I would say average grain is about 40.
