Determine the mass of the air contained in a room whose dimensions are 15 ft x 20 ft x 20 ft. Assume the density of the air is 0.0724 lb/ft3.

The reservoir in Figure contains water and immiscible oil at a temperature of 20 ° C. What is the height h in centimeters if the density of the oil is 898 kg / m3?

You are making banana bread and the recipe calls for 3/4 cup of vegetable oil and one egg yolk. You measure out your oil in a measuring cup and then just toss the egg yolk into the oil before mixing with the dry ingredients. The egg yolk has a mass of 9.9 grams and floats with 71 % of its volume under the surface of the oil. You also know that the density of the oil is Poil 0.95 cm³ What volume of oil is displaced by the egg yolk? cm3 What is the total volume of the egg yolk? cm³ What is the density of the egg yolk? g cm3 Imagine the egg yolk was floating in a salt-water solution instead (Pwater = 1.04 % .). What percentage of the yolk would be submerged in water? cm³

What is the pressure of the gas in the cylinder, in kPa (kiloPascal)? h = 0.620 m, Pmercury = 13,600 kg/m3, 1.0 atm = 1.00 x 105 Pa = 100 kPa, and g = 10.0 m/s?. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Mercury. p = 13,600 kg/m² Pen
