question #1 pls
assume stick is vertically inserted Consider a horizontally-positioned right circular cylindrical oil tank of radius r and length h as in the figure. The tanks are used for storage in various locations and are drained and filled periodically. Inventory is taken by placing a long dipstick with quarter-inch marks vertically in the tank, and then measuring the liquid level w. 1 1). If all variables r, h, and w are in inches, use calculus to find a...

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...

The BAC is usually expressed as a percent based on weight/volume. This means that the BAC is the grams (g) of alcohol present per 100 mL of blood. For example, a BAC of 0.12% is equivalent to 0.12 g alcohol per 100 mL of blood. At 0.12%, most people are intoxicated! Typically 100 mL is referred to as 1 deciliter or 1 dL. So, 0.12% is also equivalent to 0.12 g/dL. The BAC can be calculated based on how much...

The Depth Gauge Problem Liquids are often stored in elliptical storage tanks as shown below. To measure the volume of liquid in the tank, a depth gauge (measuring stick) can be used. It is inserted into an opening at the top and the level of liquid on the gauge can be used to determine the amount of liquid in the tank. The tank has width w, height h and length len (all in meters). In the example output shown below,...

4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value. Explain your answer in clear and correct English. 16 LABORATORY EXPERIMENTS IN GENERAL CHEMISTRY ed in question 4...
