Please help with question 5
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.
