1. Find each mass & which has the greater mass. 1.0 ml mercury or 1.0 ml of water
2. Find each volume & which has greater volume. 100.g gold or 100. g water
look up the densities of the materials involved
using equal volumes, greater density --> greater mass
using equal masses, greater density --> less volume
because mass(g) = density(g/ml) * volume(ml)
To find the mass of a substance, you need to know its density. Density is the ratio of mass to volume.
1. For the first question, let's find the mass of 1.0 ml of mercury and 1.0 ml of water:
- Mercury's density is approximately 13.6 g/ml.
- Water's density is approximately 1 g/ml.
To find the mass, you multiply the density by the volume:
- Mass of 1.0 ml of mercury = 1.0 ml * 13.6 g/ml = 13.6 grams of mercury
- Mass of 1.0 ml of water = 1.0 ml * 1 g/ml = 1 gram of water
From the calculations, we can determine that 1.0 ml of mercury has a greater mass than 1.0 ml of water because it has 13.6 grams compared to 1 gram.
2. Similarly, for the second question, let's find the volume of 100 g of gold and 100 g of water:
- Gold's density is approximately 19.3 g/ml.
- Water's density is still 1 g/ml.
To find the volume, you divide the mass by the density:
- Volume of 100 g of gold = 100 g / 19.3 g/ml ≈ 5.18 ml
- Volume of 100 g of water = 100 g / 1 g/ml = 100 ml
From the calculations, we can determine that 100 g of water has a greater volume than 100 g of gold because it occupies 100 ml compared to approximately 5.18 ml.
