Answer:
weight = 42.8 g
Explanation:
given data
volume = 2 liters
molarity = 0.100
KIO3 molecular weight = 214
to find out
weigh out
solution
we know that Molarity that is express as to get mole
molarity = Mol of solute ÷ solution volume ........1
put here value we get
Mol of solute = 0.100 × 2
Mol of solute = 0.2
and
mol is express as
Mol =Weight ÷ Molecular weight .............2
put here value
weight = 0.2 × 214
so weight = 42.8 g
Answer:
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
