Question

You are given a recipe for a buffer that contains 5% (w/v) MgSO4.7H2O. However, you only have MgSO4 anhydrous available to you. How much MgSO4 anhydrous do you need to make 0.5L of the buffer with the same molar concentration as in the recipe? Show your calculations

Answer 1

Can you do the buffer part.
To convert from g MgSO4.7H2O to MgSO4, it's grams MgSO4.7H2O needed x (molar mass MgSO4/molar mass MgSO4.7H2O) = ?

Answer 2
