The movement of salt molecules in a system and surroundings that have different concentrations follow the osmosis principle. Osmosis is the phenomena where molecules move from lower concentration to higher concentration through a sem-permeable membrane. when the concentration is higher outside, then answer is C. molecules <span>move out of the cell, and the cell will shrink or shrivel.</span>
To determine the mass of elemental iron in the elixir, we need to understand the given values given above. We are given the following:
Mass of ferrous sulfate = 220 mg
Volume of the elixir = 5 mL
Mass of elemental iron / mass of ferrous sulfate = 0.2 mg Fe / mg ferrous sulfate
Therefore, from the given values, we simply multiply the mass of the ferrous sulfate in the elixir and the equivalent mass of elemental iron per mass of ferrous sulfate. We do as follows:
Mass of Fe = 220 mg ferrous sulfate ( 0.2 mg Fe / mg ferrous sulfate )
Mass of Fe = 44 mg
