Answer:
Mass of CaBr₂ = 179.9 g
Explanation:
Given data:
Volume of CaBr₂ solution = 450.0 mL (450/1000 = 0.45 L)
Molarity of solution = 2.00 M
Mass of CaBr₂ = ?
Solution:
Formula:
Molarity = number of moles / volume of solution in L
Now we will put the values.
2.00 M = number of moles / 0.45 L
Number of moles = 2 M × 0.45 L
Number of moles = 0.9 mol ( M = mol/L)
Mass of CaBr₂:
Mass of CaBr₂ = number of moles × molar mass
Mass of CaBr₂ = 0.9 mol × 199.89 g/mol
Mass of CaBr₂ = 179.9 g
