How do you find mass with specific weight?
Calculating Mass From Specific Gravity
In the imperial system,
multiply by 1.94 slug/ft
3
, which is the density of water in slugs. Once you know density, you can calculate mass per unit volume. All you have to do is multiply that density by the volume of the solid or liquid to find the mass of the solid or liquid.
How do you find the specific weight of a liquid?
The SI unit for the specific weight is
N/m
3
while the English unit is lb/ft
3
. Specific gravity is simply the ratio of the specific weight of a given liquid to the specific weight of water at 4° C (γ
water
= 9.81 kN/m
3
or 62.4 lb/ft
3
). This definition is helpful when comparing densities of different liquids.

Is specific weight and specific gravity the same?
What is the difference between Specific Gravity and Specific Weight?
Specific gravity is a dimensionless quantity whereas specific weight has dimensions
. The specific gravity of a material is independent of the gravitational field, but the specific weight of a material is dependent on the gravitational field.
What is mercury’s unit weight?

What is the weight density of mercury?
Mercury is a very dense, heavy, silver-white metal that is a liquid at room temperature. (For more information about mercury, click here.) Mercury has a density of
13.5 g/mL
, which is about 13.5 times denser than water (1.0 g/mL), so a small amount of mercury like this feels unexpectedly heavy.
How do you calculate specific gravity?
The formula for specific gravity, given that the reference substance is water, is
the density of the object divided by the density of the water.
How do you find the specific gravity weight of a liquid?
Multiply the specific gravity by the volume in cubic centimetres to
get the mass in grams. To get the “weight” in Newtons, multiply by the local value for g which varies slightly across the Earth’s surface but is always close to 9.8 m/s2.
What is specific weight in physics?
Definition of specific weight
:
the weight of a substance per unit volume in absolute units equal to the density multiplied by the acceleration of gravity
.

9.807 kilonewtons per cubic metre
or 62.43 pounds-force per cubic foot.
What is the density of mercury in lb ft3?
3 One cubic centimeter (cm3) is equivalent to one milliliter (mL). temperature is
62.4 lb/ft3
. The specific gravity of mercury is 13.56.
What is the specific weight of one Litre of liquid which weight is 7n?
Let’s calculate the specific weight, density, and specific gravity of 1 L of the liquid that weighs 7 N. Hence, the specific weight is
7000 N/m3
. Then, the density is 713.5 kg/m3. Hence, the specific gravity is 0.7135.
How much does 1ml of mercury weigh?
One milliliter of mercury converted to gram equals to
13.53 g
. How many grams of mercury are in 1 milliliter? The answer is: The change of 1 ml ( milliliter ) unit of a mercury amount equals = to 13.53 g ( gram ) as the equivalent measure for the same mercury type.
How do you calculate density from specific gravity?
Converting a specific gravity into a density is as simple as
multiply the SG by the reference density for which it was based
. In most cases, this is the density of water, and therefore your multiply the SG by 1 to yield your density in g/cm^3.
How do you calculate unit weight of water?
In short, 1
mL (milliliter) of water has a mass of 1 g
, so 1 liter has a mass of 1 kg. You can use this fact to work out the mass of water from any volume: for example, 450 mL is 450 g, and 1.35 liters is 1.35 kg.

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.
How do you find weight from volume?
- % w/v = g of solute/100 mL of solution.
- Example 1:
- Example 1:
- X % = 7.5 g NaCl/100 mL of solution.
- X/100 = 7.5/100.
- 100X = 750.
- X = 7.5% w/v.
What is SG in fluids?
Specific Gravity (SG) is
the ratio of the object’s density to that of water
. Since water has a specific gravity of 1 at sea level, liquids and substances with a specific gravity lower than 1 will float in water. … These floats have low specific gravity, around .
