6.1 Mass and Density 1. 2. 3. 4. Suppose you have a coffee mug with a circular cross-section and vertical sides (uniform radius). What is its inside radius if it holds 375 g of coffee when filled to a depth of 7.50 cm? Assume coffee has the same density as water. Mercury is commonly supplied in flasks containing 76 lb. What is the volume in liters of this much mercury? Refer the appendix for the value of density for mercury. Gold is sold by the troy ounce (31.103 g). What is the volume of 1 troy ounce of pure gold? Refer the appendix for the value of density for gold. What is the mass of a deep breath of air having a volume of 2.00 L? Discuss whe will see a noticeable weight gain when you take a deep breath. you 6.2 Pressure 1. 2. 3. Assuming bicycle tires are perfectly flexible and support the weight of bicycle and rider by pressure alone, calculate the total area of the tires in contact with the ground if a bicycle and rider have a total mass of 80.0 kg, and the gauge pressure in the tires is 3.50x10 Pa. The greatest ocean depths on Earth are found in the Marianas Trench near the Philippines. Calculate the pressure due to the ocean at the bottom of this trench, given its depth is 11.0 km and using the density of seawater. What pressure is exerted on the bottom of a gas tank that is 0.500-m wide and 0.900-m long and can hold 50.0 kg of gasoline when full? 62 Ruovent forger and Archimeder principle
