Given: Mass of potassium iodate=1.00g

Volume of solution= 250 ml
Calculate the molar concentration of the potassium iodate solution.

molar mass of KIO3 = 214

since molar concentration (M) is moles/Liter,
1g/250mL * 1mol/214g * 1000mL/L = 1000/(250*214) mol/L

To calculate the molar concentration of a solution, you need to know the number of moles of solute (potassium iodate) and the volume of the solution in liters.

First, we need to determine the number of moles of potassium iodate. To do this, we can use the formula:

moles = mass / molar mass

The molar mass of potassium iodate (KIO3) is calculated by summing the atomic masses of each element: potassium (K), iodine (I), and oxygen (O). The atomic masses of K, I, and O are 39.10 g/mol, 126.90 g/mol, and 16.00 g/mol respectively.

Molar mass of KIO3 = (1 * molar mass of K) + (1 * molar mass of I) + (3 * molar mass of O)

Now, let's calculate the molar mass of potassium iodate:

molar mass of KIO3 = (1 * 39.10 g/mol) + (1 * 126.90 g/mol) + (3 * 16.00 g/mol)

Next, we can calculate the number of moles of potassium iodate using the given mass:

moles of KIO3 = 1.00 g / molar mass of KIO3

Now, we need to convert the volume of the solution from milliliters to liters. Since 1 liter is equal to 1000 milliliters, we can use the conversion factor:

volume (in liters) = 250 ml * (1 liter / 1000 ml)

Finally, we can calculate the molar concentration of the solution using the formula:

molar concentration = moles of KIO3 / volume (in liters)

Now, you can substitute the calculated values into the equation to find the molar concentration of the potassium iodate solution.
