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

Please help with question 3

OST LAB CONCLUSIONS (you may use a separate sheet of paper for calculations as well)
1. Why was something like a wooden block's density calculated by measuring the
dimensions directly and calculating the volume instead of using the displacement in
water method?
2. Measure the mass of each coin separately and record the masses below. Why were
several coins used for the density calculation instead of one.
4.90g 5.00g
4.939
4.979
5.059
3. Ethyl acetate has a characteristic fruity odor and is used as a solvent in paint lacquers
and perfumes. An experiment requires 0.985 kg ethyl acetate. What volume is this (in
liters)? The density of ethyl acetate is 0.902g/mL.
4. (EC) 70.4g of hematite (iron ore) was placed in a flask whose maximum volume was 55.0
mL. The flask with hematite was then carefully filled with water too the maximum line and
re-massed. The hematite and water had a mass of 109.3g. The density of the water was
0.996g/cm³. What was the density of the hematite?
5. (EC) The land area of Greenland is 820,000 mi2, with only 134,000 mi² free of perpetual
ice. The average thickness of this ice is 5,100 ft. Estimate the mass of the ice (assume two
significant figures). The density of ice is 0.927g/cm³.
