? atoms N = 5.00g C2H5O2N x 1 mole C2H5O2N/75.08g C2H5O2N x 1 mol N/1 mol C2H5O2N x (6.022x10^23 atoms)/1 mol N = 4.01 x 10^22 atoms N
To find 75.08g:
2C 2 x 12.01g = 24.02g
5H 5 x 1.01g = 5.05g
2O 2 x 16.00g = 32.00g
1N 1 x 14.01g = 14.01g
Add the four numbers together and you get: 1 mole of C2H5O2N = 75.08 grams
You use this as a conversion factor in the problem above.
The amount of sodium metal produced can be calculated using the law of conservation of mass. The total mass of products (nitrogen gas and sodium metal) should equal the initial mass of sodium azide. In this case, 500g of sodium azide decomposes to form 323.20g of nitrogen gas and 176.80g of sodium metal. Therefore, 176.80g of sodium metal is produced.
You will need more than just one nickel. Most scales require you to calibrate with a specific weight, usually a weight that is close to the scales capacity (ie 500g weight for 500g capacity scale) Nickels weigh approximately 5g so you would needs lots of them. However it is not exact and you will sometimes find nickels that weigh 4.9g to 5.1g. Nickels should only be used as a last ditch effort to fix a scale that is way out of calibration. You can find cheap calibration weights for pocket scales online.
The price of iodine can vary depending on the form and purity. As of May 2021, the average price for a 500g bottle of iodine flakes is around $30-50. Industrial-grade iodine typically costs less than pharmaceutical-grade iodine due to differences in purity and quality.
The water and pot(/) have a temperature increase of 100-25 degrees C that is 75 degrees. the formula Q=mass * SH* change in temperature can be used for both the water and the steel pot Hence for steel pot Q=510 j/kg/degC*.5kg*75Deg C=19125 joule. For water SH=4187 j/kg/C QW= .45*4187*75=141311 joule total heat (neglecting changes and losses to get the water to 100 deg C is 160436 joule or 160.4 kjoule. Note this does not boil the water it only raises the temperature to 100 degrees C. to boil the water requires approximately a futher 1250 kJ
C6H12O6 (180.16 g/ mol) ---> 2C2H5OH (46.07 g/mol) + 2 CO2 600.4 g glucose @ 92.14 g ethanol / 180.16 g glucose = 307.06 grams of ethanol can be produced 307.06 grams of ethanol @ 0.789g/ml = 389.2 millilitres ========= your answers: 307 grams of ethanol & 0.389 litres of ethanol
1 kg - 500g = 500g
4.72kg-500g = -495.28
Roughly 500g

1.5kg add 500g = 501.5
There are 6 units of 500g in 3kg. This can be calculated by dividing 3000g (3kg) by 500g, which equals 6.
To determine which is bigger between 500g and 12oz of lentils, we need to convert the units to the same measurement. 500g is equivalent to approximately 17.6oz, so 500g is larger than 12oz of lentils. Therefore, 500g of lentils is bigger than 12oz of lentils.
To find out how many 500g portions make up 2kg, first convert 2kg to grams: 2kg is equal to 2000g. Then, divide 2000g by 500g: 2000g ÷ 500g = 4. Therefore, there are 4 portions of 500g in 2kg.
im guessing about 500g worth?
5kg 500g is equal to 5500 grams.
half a kilogram (kgs)
500g, your welcome!
