Question

if you dissolve 25.5 g of KBr in enough water to
make 1.75 L of solution, what is the molarity of the solution

Answer 1

1 mole=119.00g

Solve for moles:

25.5g*(1 mole/119.00g)= moles of KBr

Molarity of KBr= moles of KBr/1.75L

Answer 2

Answer should contain 3-significant figures.

Answer 3

.122

Answer 4

Molar mass of KBr = 118.99
Number of moles of KBr in soulution = 25.5/118.99= 0.124 moles
molarity = Moles of KBr /L solution = 0.214/1.75 =0.1222 M
