There are 49.5g of CoCl2 in 1/2 liter used to make a 1.0 molar solution. Details about how to calculate molar concentration can be found below.
How to calculate mass?
The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.
However, the number of moles of CoCl2 must be calculated using the following formula:
no of moles = 0.5L × 1M
no of moles = 0.5moles
Molar mass of CoCl2 = 99g/mol
mass of CoCl2 = 0.5 × 99
mass of CoCl2 = 49.5g
Therefore, there are 49.5g of CoCl2 in 1/2 liter used to make a 1.0 molar solution.
