Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Question

1. A 0.4676-g sample of primary standard CaCO3
was dissolved in a final solution volume of 250.0
mL. A 25.00-mL aliquot of this solution was titrated

required 25.17 mL. Calculate the molarity of the
EDTA solution.
Give your answer to five places after the decimal
place.
2. A 25.00 mL aliquot of a 1.000-L unknown water
sample was titrated with 0.01243 M EDTA and
required 14.71 mL to reach an Eriochrome T end
point. Calculate the ppm Ca in the water sample.
Give your answer to one places after the decima
