If the radius of an element X is 0.500nm, the radii of the ions X²⁺ , X and X²⁻ formed by X is?​

The mass of KIO3 is 42.8 grams

Explanation:

Step 1: Data given

Volume = 2.00 L

Molarity = 0.100 molar

Molar  mass of KIO3 = 214 g/mol

Step 2: Calculate moles

Moles = Molarity * volume

Moles = 0.100 M * 2.00 L

Moles = 0.200 moles

Step 3: Calculate mass of KIO3

Mass KIO3 = moles KIO3 * molar mass KIO3

Mass KIO3 = 0.200 moles * 214 g/mol

Mass KIO3 = 42.8 grams

The mass of KIO3 is 42.8 grams
