Answer:

6

Explanation:

One molecule of magnesium phosphate, Mg₃(PO₄)₂, contains 2 phosphorus atoms, because P is contained between the brackets followed by a subscripted 2. If in one molecule of magnesium phosphate there are two phosphorus atoms, then in three molecules there are 3 * 2=6 phosphorus atoms.

You have an egg that has an internal 7% salt concentration and you put it into a bowl of 3% salt water. What is the tonicity of
igomit [66]

Answer:

Egg is HYPERTONIC

Water in the bowl is HYPOTONIC

The egg will become filled with water over time

Explanation:

Tonicity refers to the ability of an extracellular solution to direct the flow of a solvent (water) in and out a cell. There are three types of tonicity; hypertonic, hypotonic and isotonic. A solution is said to be HYPERTONIC when the concentration of solute in it is higher than its external solution. This is the case of the egg cell that contains 7% salt (solute).

A HYPOTONIC solution is that which contains a lower solute concentration than it's external solution. This is the case of the water in the bowl that contains 3% salt concentration.

Tonicity determines which direction osmosis occurs. Osmosis is the movement of solvent/water from a region of high solvent concentration/low solute to a region of low solvent concentration/high solute concentration via a semi-permeable membrane. In this case, water (solvent) will move through the egg cell membrane (semi-permeable membrane) from the bowl with a low solute concentration into the egg with a high solute concentration. Hence, over time, the egg cell will be filled with water.
