Is this true? Explain.

To make a 100 osmolar solution of magnesium chloride, 60g of the salt are placed in a liter of water.

To determine if the statement is true or not, we need to calculate the osmolarity of the magnesium chloride solution and compare it to the given value of 100 osmol.

1. Start by calculating the number of moles of magnesium chloride in 60g. This can be done by dividing the mass (in grams) by the molar mass of magnesium chloride, which is 95.211 g/mol.

Number of moles of magnesium chloride = 60g / 95.211 g/mol

2. Next, calculate the total number of moles of solute in the solution. Since magnesium chloride dissociates into three ions (Mg2+ and two Cl-), we need to multiply the number of moles of magnesium chloride by 3.

Total moles of solute = (Number of moles of magnesium chloride) x 3

3. Calculate the volume (in liters) of the solution. In this case, it is given as 1 liter.

4. Finally, calculate the osmolarity of the solution by dividing the total moles of solute by the volume of the solution.

Osmolarity = Total moles of solute / Volume of solution

Compare the calculated osmolarity to the given value of 100 osmol. If they match, then the statement "To make a 100 osmolar solution of magnesium chloride, 60g of the salt are placed in a liter of water" is true. If they don't match, then the statement is false.
