Respuesta :
moles HCl = 6.02 x 10^22 / 6.02 x 10^23 = 0.100
M = 0.100 / 2.00 L=0.0500
M = 0.100 / 2.00 L=0.0500
6.02 x 1022 molecules of HCl (molecular weight = 36.5 g/mole) in 2.0 liters of water. Therefore, M = 0.05
What is mole?
The SI unit for measuring the quantity of any substance would be the mole, abbreviated as mol.
Given data:
Number of molecule = 6.02 x [tex]10^{22}[/tex] molecules
Molecular weight = 36.5 g/mole
Moles = 6.02 x [tex]10^{22}[/tex] / 6.02 x [tex]10^{23}[/tex] = 0.1mol
Hence, M = 0.1 /2 = 0.05
Therefore, M = 0.05
