nd the weight of this substance needed to fill a 2 fluid ounce ointment jar in gram. If The specific gravity of white petrolatum is 0.85

Given the weight of the hot-air balloon to be 600 lb. If the heated air inside the balloon has a temperature of 160 oF while the air outside has a temperature of 85 oF, determine the required volume of the balloon to support the weight (in ft3). Assume the inside and outside air to be at standard atmospheric pressure of 14.7 psia. If the balloon had a spherical shape, what would be the required diameter (in ft)? *Use 1 decimal place on partial and final answers.

120 L of hydraulic oil have a mass of 110 kg. For the oil, calculate the Specific Gravity, SG. (Hint: first calculate the Density and the Specific Weight). Group of answer choices 0.862 0.985 0.807 0.917 0.906

515. If the specific gravity of the unknown fluid is 13.7, what is its specific weight in lbf/ft3
