Explanation:
Answer: The Answer is 18.7ml.
Explanation: Solved in the attached picture.
Answer: 16.32 g of 
as excess reagent are left.
Explanation:
To calculate the moles :
According to stoichiometry :
2 moles of 
require = 1 mole of
Thus 0.34 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
Moles of left = (0.68-0.17) mol = 0.51 mol
Mass of 
Thus 16.32 g of as excess reagent are left.
Answer: Mass
<em>Input:</em> Mass is a measure of the quantity of matter in an object.
Explanation: Mass is the measure of amount of matter in a certain object.
