Question

What is the mass, in grams, of 28.33 cubic centimeters of pure water at room temperature? Note: The density of pure water at room temperature is 1 g per mL, exactly.

Also, a cube of unknown metal measures 1.8 in by .60 in by 1.2 in and has a mass of 189.65 g. What is the identity of the unknown metal?

must show work for both

Answer 1

1mL = 1 cm^3 massing ? = V = 28.33 cm^3 delta = m/v 1 g/mL times 28.33 cm^3 = m m = 28.33 mL times 1 g/LmL m = 28.33g 1l = 1000 mL 1L = 1000 cm^3 1L = 1000 mL 28.33 cm63 = 28.33
