A metal sphere weighing 15.45 g is added to 21.27 mL of water in a graduated cylinder. The water level rises to 24.78 mL. Calculate the density of the metal. An empty beaker weighs 32.4257 g. A 10-mL pipet sample of an unknown liquid is transferred to the beaker. The beaker weighs 40 1825 g when weighed with the liquid in it. Calculate the density of the unknown liquid.

1. Density of Metal = 4.40g/cm³

2. Density of Liquid = 0.77568g/cm³

Explanation:

1.

Given

Initial Volume of Water = Vi = 21.27mL

Volume of Water = VF = 24.78 mL

Mass of Sphere= 15.45 g

Density = Mass/Volume

Change in Volume = 24.78 - 21.27 = 3.51 mL

Density = 15.45/3.51

Density = 4.40g/ml

1ml = 1cm³

So, density = 4.40/cm³

2.

Initial Mass of Beaker = Mb = 32.4257g

Final Mass of Beaker = Mf = 40.1825 g

V = 10 mL

Density = D = ?

Change in Mass =: MF – MI= 40.1825 – 32.4257 = 7.7568 g

Density = Mass/Volume

Density = 7.7568g/10mL

Density = 0.77568g/mL

1mL = 1cm³

So, density = 0.77568g/cm³

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
