Specific gravity calculator helps to measure the specific gravity of substance. It is defined as the ratio of weight of a certain volume of material to the weight of the water of the equal volume. Specific gravity can also be defined in terms of density, when density is the amount of mass in a given volume. Specific gravity of a fluid compared with an equal volume of water.The formula for specific gravity is given as,

Specific gravity = $\frac{Density\ or\ mass\ of\ the\ substance}{Density\ or\ mass\ of\ the\ water}$

**Step 1:**Note down the given values in the question

**Step 2:**According to the given values, use the equation and find out the unknown value.

Specific gravity = $\frac{Density\ or\ mass\ of\ the\ substance}{Density\ or\ mass\ of\ the\ water}$

Solved problems based on specific gravity are discussed as follows.

### Solved Examples

**Question 1:**Calculate the specific gravity of a 150 g stone which is immersed in 50 g of water?

**Solution:**

Given that,

Mass of the stone = 150 g

Mass of the water = 50 g

Specific gravity can be calculated using the formula,

Specific gravity = $\frac{Mass\ of\ the\ substance}{Mass\ of\ the\ water}$

Specific gravity = $\frac{150}{50}$ = 3

**Question 2:**A stone is dipped in 100 g water. The specific gravity of stone is given as 1.5 units. Calculate the mass of the stone?

**Solution:**

Given that,

Mass of the stone = ?

Mass of the water = 100 g

Specific gravity = 1.5 units

Specific gravity can be calculated using the formula,

Specific gravity = $\frac{Mass\ of\ the\ substance}{Mass\ of\ the\ water}$

Mass of the substance = Specific gravity$\times$mass of the water

Mass of the stone = 1.5$\times$100 = 150 g
