A 4.369 g sample of metal is placed in a flask.Water is added to the flask and the total volume in the flask is read to be 126.4 ml.The mass of the water,flask,and metal is 268.5 g.If the mass of the flask is 139.3 g and the density of water is 1.000 g/mL,the density of the solid is ________ g/cm³. A)0.366 B)1.56 C)0.641 D)2.78 E)3.21

To find the density of the solid, we first need to calculate the volume of the metal. We can do this by subtracting the volume of water from the total volume in the flask. The mass of the water can be found by subtracting the mass of the flask and metal from the total mass, then using the density of water to find its volume. The density of the metal is then the mass of the metal divided by its volume.1. Mass of water + flask + metal = 268.5 g2. Mass of flask = 139.3 g3. Mass of metal = 4.369 g4. Total volume in flask = 126.4 mLMass of water = Total mass - (Mass of flask + Mass of metal) = 268.5 g - (139.3 g + 4.369 g) = 124.831 gSince the density of water is 1.000 g/mL, the volume of water is 124.831 mL.Volume of metal = Total volume - Volume of water = 126.4 mL - 124.831 mL = 1.569 mLDensity of metal = Mass of metal / Volume of metal = 4.369 g / 1.569 mL = 2.78 g/cm³
