Calculate the amount of sodium chloride, NaCl, in 55.0cm3 concentration 0.5mol/dm3
Question
Calculate the amount of sodium chloride, NaCl, in 55.0cm3 concentration 0.5mol/dm3
Solution
To calculate the amount of sodium chloride, we need to use the formula:
Moles = Concentration x Volume
First, convert the volume from cm3 to dm3 because the concentration is given in mol/dm3.
1 dm3 = 1000 cm3
So, 55.0 cm3 = 55.0/1000 dm3 = 0.055 dm3
Now, we can substitute the values into the formula:
Moles = 0.5 mol/dm3 x 0.055 dm3 = 0.0275 mol
The molar mass of NaCl is approximately 58.44 g/mol.
So, the amount of NaCl = Moles x Molar mass = 0.0275 mol x 58.44 g/mol = 1.6071 g
Therefore, the amount of sodium chloride is approximately 1.61 g.
