i dont knowww
A billion is a thousand-million. Metric Units: Deca - Ten Hecto - Hundred Kilo - Thousand Mega - Million Giga - Billion Tera - Trillion Many of the prefixes are uncommonly used. But, say, for example you had a billion grams (gigagram) and you wanted to convert it to megagrams, you would multiply it by 1000. So... one gigagram would be 1000 megagrams. Now, it gets a little more complicated when one talks about computers. Computers are based on factors of 2. 210 = 1024 which is the "standard" base for many computer calculations, especially those using metric prefixes. So, a kilobyte would be 1024 bytes. a megabyte is 1024 kilobytes, or 1024*1024 bytes = 1,048,576 bytes a gigabyte is 1024 megabytes, or 1024*1024*1024 bytes = 1,073,741,824 bytes. a terabyte is 1024 gigabytes, or 1024*1024*1024*1024 bytes = 1,099,511,627,776 bytes.
Convert everything to the same unit, the divide. Please note that 1 GB = 1024 MB, and 1 MB = 1024 KB.
1024 * 1024 = 1,048,576
The LCM is 1024.
The LCM is 1024.
200 grams H2O (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O) = 6.69 X 1024 molecules of water ======================
192.678 grams CH3OH
A cup is 8 fluid ounces. And 8 ounces is about 236.6 grams of water.There are 18 grams of water in one mole of water, and a mole of anything contains Avogadro's number of molecules of that compound. That's 6.02 x 1023 molecules.Our (236.6 grams of water) divided by (18 grams per mole) = 13.14 moles of waterOur (13.14 moles of water)(6.02 x 1023 molecules per mole) = 7.91 x 1024 molecules in the 8 ounce glass of water.We had 8 ounces of water. We converted to grams. Then we looked up water to see how many grams of water there were in a mole of water. Then we found out how many moles we had in our cup of water. Then, because we knew how many molecules of water were in a mole (we know because a mole of anything is Avogadro's number of particles of that substance), we multiply to find out how many molecules of water were in the cup of water.That's how we found that there are 7.91 x 1024 molecules in a cup of water.
1.88 X 1024 molecules SO3 (1 mole SO3/6.022 X 1023)(80.07 grams/1 mole SO3) = 250 grams sulfur trioxide ===================
The simplest form of the molecular formula for methanol {note corrected spelling} is CH4O, and its gram molecular mass is 32.04. By definition therefore, a mass of Avogadro's Number of molecules contains 32.04 grams. Avogadro's Number is about 6.022 X 1023. Therefore, 9.47 X 1024 molecules of methanol contains [(9.47 X 1024)/(6.022 X 1023)]32.04 or 504 grams, to the justified number of significant digits.
MB stands for Megabytes. To convert this to KB, multiply by 1024. To convert it to Bytes, multiply it by 1024 squared. To convert to GB, divide by 1024.
36 g (6.02 x 1023 at / 12.01 g) = 1.8 x 1024atoms
Quite a few! 427.4 grams KNO3 (1 mole KNO3/101.11 grams)(6.022 X 1023/1 mole KNO3) = 2.546 X 1024 molecules of potassium nitrate -----------------------------------------------------------
2H2 + O2 ==> 2H2O1.95x10^24 H2 molecules x 2 molecules H2O/2 molecules H2 x 1 mole H2O/6.02x10^23 molecules = 3.24 moles H2O x 18 g/mole = 58.3 g H2O
9.18x10^24 molecules CH3OH x 1 mole/6.02x10^23 molecules x 32 g/mole = 488 g (to 3 sig figs)
1 x 1024 molecules
One mole is defined by Avogadro's number of 6. 02x10^23 particles. To solve this equation we multiple Avogadro's number by our given quantity of 2. 10 moles. The answer then is 2. 64x10^24 molecules of CO2.
