A mole (sometimes expressed as "mol") is usually defined as 6.02 x 10^23, though more accurate variations do exist.
1 mol of nitrogen per 1 mol of oxygen. NO2
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
The mass in grams of one mole H2SO4 is: 98.079 g/mol (molar mass)The mass in grams of one molecule H2SO4 is (molecule mass):98.079 (g/mol) / 6.02214*10+23(molecules/mol) = 16.286*10-23 g/molecule
2.2 mol water = 2.2 (mol) * 18 (g/mol) water = 39.6 (mol*g/mol) = 40 g18 g/mol = mol mass of H2O = 2*H + 1*O = (2*1 + 16) g/mol
It weights the same as one times the molar mass in g/mol. It is NOT important to be ideal, it even needn't to be necessarily a gas, only the kind of compound is important.
7.4 mol of H2
6.022 x 1023
1 mol of nitrogen per 1 mol of oxygen. NO2

6.65X10^5 kj/mol
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
Other comment is wrong 2.5 g 1 mol/18.02 g (-285.83) kJ/mol
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
No.
58 g NaCl = 58 (g) / 58.44 (g/mol NaCl) = 0.9925 (mol NaCl) = 0.9925 (mol Cl-) = 0.9925 * 35.45 (g/mol Cl-) = 35.2 g Cl-
63.55 g/mol (63.55 grams per mole)
MOL refers to MAXIMUM OVERALL LENGTH. MOL is Maximum Overall Length measurement. MOL of bulb is measured from top of bulb to bottom of Bulb base (or bottom of pins.) Exception is if bulb has flexible wire leads, then measurement does NOT include the length of wires. Actual bulb is likely shorter (sometimes much, much shorter) than the MOL industry standard specification.
