It has a volume of: 113.03 cm 113.03 cm3 904.32 cm 904.32 cm3 A 0.016 m 3 propane gas bottle has a mass of 9 Kg when empty. After filling the bottle with propane, the mass of the bottle becomes 16 kg. The density of propane gas is: 1000 Kg 437.5 Kg 0.0022 Kg 562.5 Kg A cube (S) having a side of 4 cm, was immersed in the beaker containing 500 ml of water. When the solid (S) was immersed in the beaker containing water, some of the water was displaced and collected in a beaker as shown below (Over flew).The volume of the water that overflew is: 4cm 12cm3 16cm3 64cm3 Given a metallic nugget that has a density of 2.5 g when this nugget is inserted in 500 ml of water in a beaker, the level rises till 700 ml. The mass of this nugget is: 0.0125 g 80 g 500 g 1750g The following document represent a density tower that contains:Colored water, corn syrup, oil, piece of cork, a plastic block, and one grape.Choose the correct statement: The syrup has the least density. The cork has the largest density. The grape has less density than syrup but greater density than water. The density of oil is greater than the density of water. Grade seven students are given a nugget to form the following measurements:The digital balance indicates 482.63 g. The volume of water before inserting the nugget was 600 mL. After inserting the nugget, the volume becomes 800 mL.The density of this nugget is: 2.41 g 0.6 g 0.41 g 0.80 ml The following document represents a graduated cylinder that contains:400 ml of waterA marbleA cylinder of volume equals to 160 cm3 The final volume of the water, marble, and the cylinder is 600 ml.Calculate the volume of the marble: 160 cm3 40 cm3 200 ml 440 ml A marble has a mass of 510 g and volume of 30 cm3.It has a density in SI: 17 g 17 Kg 17000 Kg 17000 Kg You have a golden bracelet that has a mass of 10gThe density of gold is 19.3 g volume of the bracelet is: 1.93g 0.51 cm3 0.51 g 193 cm3 You have an unknown object that has a mass 430 g and 20 cm3. Using the following table, indicate its nature:MaterialDensity (g Platinum Iron Silver Copper The helium gas is: Expandable but in compressible Compressible but not expandable Compressible and expandable None of the above The following document represents how to measure the mass of some air.The mass of the air measured in milligrams (mg) is: 0.08 mg 0.008 mg 80 mg 0.00008 mg The volume of the water in the following graduated cylinder is: 65 mL 53 mL 56 mL 60 mL The volume of a cylinder is calculated using the following formula: V = 4 πr3 V= πr2h V= πrh2 V = 3 πr3
