Hello people! I was wondering if you could help me solve this problem. I know it must be simple  but I am new in this whole analytical chemistry and I feel a bit confused- I would appreciate it


1. Calculate the number of millimoles contained in 500 mg of BaCrO4

2. Calculate the number of grams that would have to be dissolved and diluted to 100 mL to prepare a 0.200 M solution.

What formulas combining molar mass, mass and number of moles do you know?
