How do you calculate specific gravity from weight in air and water?

When a gem stone is weighed in air and then weighed in water the loss of weight is equal to the weight of its volume in water displaced. The weight of the gem in air divided by the loss of weight in water gives the specific gravity of the stone.

What is the specific gravity of the stone if the stone weighs 650 N in air and 275 N in water?

A stone weighs 650 N in air and 275 N in water. Compute its specific gravity. specific gravity= Density of stone/Density of water=1.73.

What is the weight of stone in water in Newton?

A stone weighs 392.4 N in air and 196.2 N IN the water.

What is the weight of stone in air?

Weight of stone in air=272g.

What is buoyant force Mcq?

The resultant force on a body due to the fluid surrounding it. Equal to the volume of liquid displaced.

What is the weight of a stone in air?

How do you calculate the weight of a stone in air?

Medium X is “salt solution”, medium Y is “air” and medium Z is “water”. 1 kg mass in air = 10N. ∴ Weight of the stone = 1.8 kg….

Medium	Weight
Z	14 N

Is a stone heavier than water?

Rocks are heavier because they sink in the water. Air is lighter than water, so balls float in the water. This is a force known as buoyancy; objects that are lighter than the surrounding gas or liquid floats, Baloons float in the air because they are filled with helium, which is lighter than air.

What is the specific gravity (SG) of a stone?

A stone weighs 200 N in air and 120 N in water. What is the specific gravity (SG) of the stone? Specific gravity is Weight of the item (in air) / Weight of water displaced when the item is placed in water = the weight in air/ (weight in air – weight in water)

What is the volume of the stone in the water?

For water, Weight in air = 2.5 N and loss of weight is 1.0 N which implies that the volume of the displaced water has a weight equal to 1.0 N. The mass of the stone is 2.5 N / 9.8 m/s^2 = 0.255 kg. The volume of the stone is 0.102 liters.

What is the weight of the stone in liters?

Weight is mass times acceleration due to gravity. For water, Weight in air = 2.5 N and loss of weight is 1.0 N which implies that the volume of the displaced water has a weight equal to 1.0 N. The mass of the stone is 2.5 N / 9.8 m/s^2 = 0.255 kg. The volume of the stone is 0.102 liters.

What is the weight of a marble placed in water?

This means that 40 cc of water is displaced when a marble is placed in it. The density of water is 1g/cc so the weight of displaced water is 40g. Buoyant force is 40g thus the weight of the marble will be 100–40=60g. If the weight of water and the weight of air is given, how do you find a specific gravity?
