How many moles of atoms are in 382 g Co?
The answer is 6,482 moles.
How many moles of SO2 are present in 250.0 g?
Number of moles is determined by dividing molar mass into the number of grams. SO2 has a molar mass of 64.066 g. To find the number of moles in 250.0 g of SO2, divide 250.0 g by 64.066 g. This gives you just over 3.9 moles.
How many moles of atoms are contained in 382g Co?
How many moles of atoms are contained in 382 g Co
How many moles are present in 128 grams of sulphur dioxide?
Divide mass of 128 g SO2 by its molar mass of 64.066 g.mol−1 SO2 and you get the number of moles: 1.9979 = 2.00 mole SO2
How many moles are there in 2.56g of So2?
Assuming that the questioner meant "SO2" instead of the nonexistent "So2": The gram molar mass of SO2 is 64.06. Therefore, 2.56 g contains 2.56/64.06 or 3.97 X 10-2 mole, to the justified number of significant digits.

What number of moles of o2(g) is required to react with 3.6 mole so2(g) in 2so2(g) o2(g) - 2so3(g)?
1,8 moles of oxygen are necessary.
How many moles are there in 2.56g of So2?
Assuming that the questioner meant "SO2" instead of the nonexistent "So2": The gram molar mass of SO2 is 64.06. Therefore, 2.56 g contains 2.56/64.06 or 3.97 X 10-2 mole, to the justified number of significant digits.
How many moles are present in 2.56g of So2?
#1 Remember the moles equation , which is moles = mass(g) /Mr #2 Mr is the relative molecular mass of the given substance. For SO2 it is' 1 x s = 1 x 32 = 32 2 O = 2 x 16 = 32 32 + 32 = 64 Hence substituting moles(SO2) = 2.56g / 64 = moles = 0.04 moles NB When writing chemical formula, single letter symbols are ALWAYS a CAPITAL letter. Hence sulphur is 'S' and oxygen is 'O'. NOT 'o' A double letter symbol is written as , 1st leter is a capital letter and the second letter is small / lower case. e.g. Sodium is 'Na'.
How many molecules are in 32 g of SO2?
32 g SO2 x 1 mole SO2/96 g x 6.02x10^23 molecules/mole = 2.0x10^23 molecules
Which reaction would cause a increase in entropy?
CH4g + H2Og COg + 2H2g
What is the equilibrium constant for the reaction so2 (g) no2 (g) so3 (g) no (g)?
SO2(g) + NO2(g) ==> SO3(g) + NO(g)Keq = [SO3][NO]/[SO2][NO2] Without knowing concentrations, one cannot calculate the actual value of Keq.
How many grams are contained in 4.56 moles of krypton Kr?
4.56 moles Kr x 83.798 g/mole = 382.119 grams = 382 grams (to 3 significant figures)NOTE: You should not use more than 3 significant figures since 4.56 moles limits the precision. Thus the answers of 381.66g and 382.1188 g are incorrect.
