First, we need to calculate the mass of the mercury in the bottle:
Mass of water = 45g
Mass of mercury = 360g
Mass of mercury = Total mass - Mass of empty bottle
Mass of mercury = 360g - 20g = 340g
Next, we need to calculate the volume of the mercury in the bottle by using the density formula:
Density = Mass / Volume
Since we know the mass of the mercury is 340g and the density of mercury is approximately 13.6 g/cm^3, we can calculate the volume of the mercury:
340g = 13.6g/cm^3 x Volume
Volume = 340g / 13.6g/cm^3 = 25 cm^3
Therefore, the density of mercury is 13.6 g/cm^3.
A bottle full of water has a mass of 45g when full of mercury its mass is 360g if the mass of the empty bottle is 20g calculate the density of mercury

An investor wanted to buy the land to use it for business two boys jesse and david had pieces of land which they wanted to sell but they would argue that one has a bigger piece than the other as a phsics student help these boys to stop arguing and invest to pay for the pieces of land correctly if an hectare of land is 1000metres sq and it is bought ay 10millions
To determine the size of each boy's piece of land and how much they should be paid based on the size, we can follow these steps:
1. Jesse's piece of land:
If Jesse's piece of land is represented by x hectares, then the size of Jesse's land in square meters would be 1000x square meters.
2. David's piece of land:
If David's piece of land is represented by y hectares, then the size of David's land in square meters would be 1000y square meters.
Given that an hectare of land is 1000 square meters and the cost of 1 hectare is 10 million, we can calculate the cost of Jesse's and David's land.
Cost of Jesse's land = 10,000,000 * x
Cost of David's land = 10,000,000 * y
To avoid arguments, we can set up the condition that both pieces of land are equal in value. Therefore, the cost of Jesse's land should be equal to the cost of David's land:
10,000,000 * x = 10,000,000 * y
Solving for x gives:
x = y
This means that both Jesse and David should be paid the same amount for their pieces of land, regardless of the size because the cost per hectare is the same. So, both Jesse and David should be paid 10 million for their land.
