Hi, I don't necessarily need the answers, although those would be great, I am more concerned with how to work out these next few problems. There were about 20 of these types of problems, I was able to figure most out but really dont know how I did it. These are the ones I don't even know where to start on.
1. What is the volume (in Liters) of a room with dimensions of 2.80m X 10.6m X 16.5m?
2. The average liter of saltwater contains 40g of dissolved tonic compounds like NaCl. If the efficiency of an evaportive process designed to extract salts is 46%, how many kg of total salt are produced by processing 2.50 X 10 to the 2 cumic meters of saltwater? Answer in kg.
3. A cylindrical glass tube 13.3cm in length is filled with mercury (Density= 13.6g.mL). (The volume of a cylinder ofradius (r) and length (h) is V=pie(rsquared)h). The mass of mercury needed to fill the tube is 104.5g Calculate the inner diameter of the tube. Answer needs to be in cm.
4.A sheet of aluminum foil has a total area of 1.000ft squared and a mass of 3.191g. What is the thickness of the foil in mm? (Density of aluminum is 2.699g/cm cubed).
If a 0.10-mL volume of oil can spread over a surface of water of about 42.0cm squared in area, calculate the thickness of the layer in cm squared?
