The mass of Calcium bromide added in the flask is 29.7 g.
<h3>What is Molarity? </h3>
Molarity is defined as the ratio of number of moles od solute to the number of volume of solution in litres.
Molarity = number of moles/ volume
<h3>Calculation of Moles</h3>
Number of moles = Molarity × volume
Given,
Molarity of Calcium bromide = 0.363 M
Volume of Calcium bromide = 410 mL
= 0.410L
By substituting all the value, we get
Number of moles = 0.363 × 0.410
= 0.148 mol
As we know that,
Molar mass of Calcium bromide = 199.89 g
<h3>What is Mole? </h3>
Mole is defined as the given mass of substance to the molar mass of substance.
Given mass = Moles × Molar mass
= 0.148 × 199.89
= 29.75 g
= 29.7 g (significant digit)
Thus, we calculated that the mass of Calcium bromide added in the flask is 29.7 g.
