Question

Osmium has a density of 22.78 grams/cm. The mass of a weighing boat is tared to zero and the mass of a piece of osmium and the weighing boat is 103.752 grams. If the piece osmium is added to 47ml of water in a 100ml graduated cylinder, to what volume reading will the water leve nd the n of osmium is added to 47 ml l rise in the cylinder

Answer 1

The weighing boat was tared to 0 grams, therefore, when the osmium metal was placed on the weighing boat, the mass of 103.752 g = mass of osmium!!

Use the mass of osmium and its density to calculate volume of Os. I believe your density value has a typo = 22.78 g / cm³. Note 1 cm³ = 1 mL

d = m / V

V = m / d = 103.752 g x (1 mL / 22.78 g) = 4.55452 mL

When osmium is added to 47 mL of water in the grad cylinder, the final volume = 47 + 4.55452 = 52 mL (rounded to 2 significant figures)
