The molar mass of monotonic Nitrogen is 14 g/mol. Since this is diatomic Nitrogen, double that to 28 g/mol.
Next, divide total mass by molar mass, 500 g / 28 g/mol, which gives <span>17.8571 moles. A mole is defined as being 6.022*10^23 molecules, so multiply moles by molecules/mol (Avogadro's number), and we finally end up with something like 1.075 * 10^25, give or take a few billion particles.</span>
<span>An Inference Is An Idea Or Conclusion Thats Drawn From Evidence And Reasoning. An Inference Is Also An Educated Guess.</span>
Answer:
Here is a similar question ; Identify the numbers from the statements above as exact or measured Sort these numbers into the proper categories. 93 g of silver, One minute, 2.20 lb ,One kilogram ,27 miles ,One yard, 100 g of sterling silver ,60 s, 1gal ,3 ft Exact Measured
Explanation:
Here is a similar question ; Identify the numbers from the statements above as exact or measured Sort these numbers into the proper categories. 93 g of silver, One minute, 2.20 lb ,One kilogram ,27 miles ,One yard, 100 g of sterling silver ,60 s, 1gal ,3 ft Exact Measured
Exact number are known from scientific research that has been proven to be true and widely acceptable or are known from true definition. for example 0 degree celsius = 273k, 1atm = 101.325 kPa
while measured numbers are not widely acceptable, they are as a result of individual measurement and discretion. A may measure the mass of a stone to be 3.5g, another person B may measure the same stone and arrive at 3.4g.
- exact numbers ; one minutes, One yard, One kilogram, 1gal, 3ft, 100g of sterling silver
- measured numbers ; 93g of silver, 2.20 lb, 27 miles
Using the Bronsted-Lowry (B/L) Theory tell which is the acid and which the base in .... (c) [H+<span>] = </span>8.1x10-10M [OH-] = 1x10-14/8.1x10-10<span> = 0.12x10</span>-4<span> = 1.2x10</span>-5M ... (c) [OH-] = 4.5x10-7M [H+] = 1x10-14/4.5x10-7<span> = 0.22x10</span>-7<span> = 2.2</span>x10<span>-8</span><span>M</span>
