Question

A coffee cup is found to have a volume of 258 milliliters. Using unit analysis, show what the volume of the coffee cup is in cubic centimeters, cm3. 258 mL x (number) (unit) cm3 (number) (unit)

Answer 1

Ars-1 258 m2 to cm3 ImL = 1 m3 = 258 m2 x 1 cm3 = 258 cm3 Imt 258 mL = 258 cm3

Ansa llog to my lg = 1000 mg 110x 1000 mg = 110000 mg Ans 23. mass= 396.6g volume = 18.3mL Density= maxs - 396.68 = 21679lmL u volume 183 m g The metal is most likely = Platinum Because in table Platinum density is 21:46 gime and it is nearest to our answer. . Ansay Tolume of aluminium = 19.1m2 density of aluminium = 2.72 g/mL (asper table ) mass of aluminium= ? Density = mass mass = Density x volume 5 mass of alumimicem = 2072 8 x 19.1997 - 51.959 AL

20=? - 19:28 g 1 mL (As per table Ansos a volume occupied by gold = ? mass of gold = 18.3 g density of gold = 19:28 g/mL . density = mass - volume = mass » volume density volume Occupied by gold = 3 18.39 x mL = 0.95mL 19.288
