Find the numbers of moles in 100 kg of sodium?
The numbers of moles in 100 kg of sodium is 4 349,76.
How many atoms does 0.5 kg sodium contain?
First calculate the moles of sodium moles = 500 g/ 23 = 21.739 ... Remember the Avogadro Number. 6.022 x 10^(23) is the number of atoms in one mole Hence , multiplying 6.022 x 10^(23) X 21.739... = 1.309 x 10^(25) atoms in 0.5 kg of sodium .
How many moles of gold atoms are there in 12.4439 kg of gold?
12,4439 kg of gold contain 63,177 moles.
How many moles of NaN03 are in a 2.70 m solution made with 3250g of H2O?
2.70 m = 2.70 moles/kg solvent3250 g solvent = 3.25 kg solvent2.70 moles/kg x 3.25 kg = 8.775 moles NaNO3 = 8.78 moles NaNO3 (3 significant figures)
How many kg are in 125.0 moles of lead 2 hydroxide?
The answer is 30,151 kg.
What is the molality of a solution containing 1330g of methanol and 16.6g of sodium bromide?
Molality denotes the number of moles of solute per kilogram of solvent. The molar mass for sodium bromide is 102,9 g/mol. nNaBr= 16,6 g/ 102,9 g/mol = 0,16 moles The concentration of the solution is therfore = 0,16 moles/ 1,330 kg = 0,12 molal -While the above is true it should 0.121 molar due to significant digits (just a technicality)
How many kg are in 125.0 moles?
