3. Suppose you have a rock with a mass of 305 g. When attached to a spring scale and lowered completely into water the spring scale reads Fe 2.10 N. Note that this reading is significantly lower than the rock's weight Fo Mg (3 N), because of the buoyant force helping to support it. From this information, calculate the following: (a) Fe: the magnitude of the buoyant force exerted on the rock. Use N2L in conjunction with the FBD shown...

1. ***present all the calculations*** Part I: The density of seawater is approximately 1.027g / cm3 and the ice density 0.93g / cm3. United Nations Iceberg (iceberg), generally has a mass of 150,000 metric tons (1 metric ton = 1000kg). Calculation (a) The buoyant force exerted by the water on the "iceberg", (b) the volume of the iceberg above sea level, (c) the volume fraction above sea level. Part II: A metal bucket with a height of 0.700 m and...

An ethanol-water solution is 40.00% ethanol by mass and has a density of 0.9450 (g/cm3) at 25.00°C. The density of pure ethanol is 0.7850 (g/cm3) and the density of pure water is 0.9970(g/cm3) at this temperature. At these conditions, the partial molar volume of ethanol is 55.00 (cm3/mol) and the partial molar volume of water is 17.5 (cm3/mol). a. Calculate the total volume of a 1000.0 g solution assuming both ideal and non-ideal conditions. b. What does the difference between...

I need help with lab this week. I have posted theory and procedures to the lab. The questions with ????????? are the ones I need help with. Please Help!! Thank you Theory Density is defined as mass per unit volume that has a metric unit of kg per cubic meter. Grams per cubic centimeter i.e. g/cm3 actually is widely used as the unit of density. The densities for objects with regular shapes are easily to be determined. For objects with...
