The answer to your question is 500 ml
Explanation:
Data
Volume = ?
mass of CuSO₄ = 11-2 g
concentration = 0.14 M
Process
1.- Calculate the molar mass of CuSO₄
CuSO₄ = 64 +32 + (16 x 4)
= 64 + 32 + 64
= 160 g
2.- Calculate the number of moles
160 g of CuSO₄ 1 mol
11.2 g of CuSO₄ x
x = (11.2 x 1)/160
x = 0.07 moles
3.- Calculate the volume
Molarity = moles/ volume
Solve for volume
Volume = moles/Molarity
Substitution
Volume = 0.07/0.140
Simplification
Volume = 0.5 L
Result = 500 ml
We need 501 mL to dissolve 11.2 grams of CuSO4
Explanation:
Step 1: Data given
Mass of CuSO4 = 11.2 grams
Molarity CuSO4 = 0.140 M
Molar mass = 159.61 g/mol
Step 2: Calculate moles CuSO4
Moles CuSO4 = mass CuSO4 / molar mass
Moles CuSO4 = 11.2 grams / 159.61 grams
Moles CuSO4 = 0.0702 moles
Step 3: Calculate volume
Volume = moles /molarity
Volume = 0.0702 moles / 0.140 M
Volume = 0.501 L
We need 501 mL to dissolve 11.2 grams of CuSO4
