What is the mass of a grain of sand?

Mass of a Grain of Sanddiameter=0.060 mmvolume=2.51 × 10−10 m3mass=6.66 × 10−4 g → 0.67 mg

How much does the average grain of sand weigh?

How much one sand grain weighs? Let’s assume that we are dealing with quartz grains. Quartz has a density of 2.65 grams per cubic centimeter. A grain with a diameter of 2 millimeters makes up only little more than four thousands of a cubic centimeter, and it weighs approximately 0.011 grams.

How many grains of sand is a billion?

At the other end of the scale, big sandcastles are several feet long, wide, and tall, and the number of grains is really big. If you picture a cube that’s 1 foot wide in each direction, that holds about a billion grains of sand — which will weigh between 50 and 100 pounds, depending on how wet the sand is.

How many grams is a grain of salt?

The atomic mass of Na is 23 gr per mole, and the atomic mass of Cl is 35.5 gr per mole. So, the average ‘atomic weight of salt’ is 29.25 grams per mole. Now it is a simple matter to find how many atoms there are in a grain of salt.

How many grains of sand are there in a cubic meter?

30,000,000 x 50 x 5 = 7.5 billion cubic meters of sand. A grain of sand is about 0.1 mm across, so there are 10,000 per meter or 10,000 x 10,000 x 10,000 (or 1,000 billion) per cubic meter. So we are talking (oh so very very roughly) about 7500 billion billion grains of sand along our Australian coastline.

What is the mass of the bacterial cell?

The bacterial flora weighs approximately 90 g and, assuming bacterial cell density is approximately 1 g ml-1, occupies a volume of 90 ml. The human body has 1013 human cells and hosts 9×1013 bacterial cells. One E. coli cell has a mass of 0.95×10−15 kg (wet weight).

How much does a single grain of sugar weigh?

How many grains of rice are in a 10kg bag?

My estimation is that there are 500,000 grains of rice in a 10kg bag. To get to this answer I researched how many grains of rice there were in one gram. I found out that there were 50 grains of rice in one gram. I then multiplied 50 by 10,000 as there are 10,000 grams in 10kg.

How many grains are in a bowl of rice?

That depends upon the thousand grain weight of the rice variety. Rice varieties have thousand grain weight ranged between 10 grams to 30 grams. So one cup of rice have grains ranging from 6000 to 18000.

How many grains of rice does it take to feed a person for a day?
