1 mole=119.00g
Solve for moles:
25.5g*(1 mole/119.00g)= moles of KBr
Molarity of KBr= moles of KBr/1.75L
Solve for moles:
25.5g*(1 mole/119.00g)= moles of KBr
Molarity of KBr= moles of KBr/1.75L

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
Hope it will help you guys ! !
