A relative density bottle weight 20g when empty 80g when filled with water and 100g when fissed with paraffin. Find the relative density of paraffin
(100-20)/(80-20) = 5/3
oops ... 4/3
To find the relative density of paraffin, we can use the formula:
Relative Density = (Weight of Substance) / (Weight of Water)
The weight of water is the weight of the filled bottle minus the weight of the empty bottle. Let's calculate it first:
Weight of Water = Weight of Filled Bottle - Weight of Empty Bottle
= 80g - 20g
= 60g
Now, we can find the relative density of paraffin:
Relative Density of Paraffin = (Weight of Paraffin) / (Weight of Water)
= 100g / 60g
≈ 1.67
Therefore, the relative density of paraffin is approximately 1.67.
To find the relative density of paraffin, we need to compare the density of paraffin to the density of water. Relative density is also known as specific gravity, and it is the ratio of the density of a substance to the density of a reference substance (usually water) at a specific temperature.
Given that the relative density bottle weighs 20g when empty, 80g when filled with water, and 100g when filled with paraffin, we can subtract the weight of the empty bottle from the weights of the filled bottle to find the weights of the substances alone.
Weight of water = 80g - 20g = 60g
Weight of paraffin = 100g - 20g = 80g
Next, we need to compare the weight of the paraffin to the weight of the water to determine the relative density.
Relative density of paraffin = Weight of paraffin / Weight of water
Relative density of paraffin = 80g / 60g = 1.33
Therefore, the relative density of paraffin is 1.33.
