if the relative density of a metal is 19.what will be the mass of 20cm3 of the metal when immersed in water
is relative mass the same as specific gravity?
if the s.g. is 19, then the apparent mass (weight) in water is
... (19 - 1) g/cm^3 * 20 cm^3
To determine the mass of the metal, we need to use the relative density and the density of water.
The relative density is the ratio of the density of the metal to the density of water. In this case, the relative density is given as 19.
Density of water = 1 g/cm^3
To find the mass of the metal, we can use the formula:
Mass = Volume x Density
Given that the volume of the metal is 20 cm^3, we can substitute the values:
Mass = 20 cm^3 x Density
From the relative density, we know that the density of the metal is 19 times that of water:
Density of metal = 19 x Density of water = 19 x 1 g/cm^3 = 19 g/cm^3
Substituting the density value into the formula, we get:
Mass = 20 cm^3 x 19 g/cm^3
Mass = 380 g
Therefore, the mass of 20 cm^3 of the metal when immersed in water is 380 grams.
To find the mass of the metal when immersed in water, you'll need to consider its relative density and the density of water.
Relative density is defined as the ratio of the density of a substance to the density of a standard substance (usually water). In this case, the relative density of the metal is 19, which means it is 19 times denser than water.
The density of water is typically considered to be 1 gram per cubic centimeter (g/cm³).
So, to find the mass of 20 cm³ of the metal when immersed in water, you can follow these steps:
1. Determine the volume of the metal in liters. Since the volume is given as 20 cm³, you need to convert it to liters. There are 1000 cm³ in a liter, so the volume in liters is 20 cm³ ÷ 1000 = 0.02 liters.
2. Multiply the volume of the metal by the density of water. The resulting value will be the mass of the water displaced by the metal. Mass = Volume × Density = 0.02 liters × 1 g/cm³ = 0.02 grams.
3. Multiply the mass of the water displaced by the metal by the metal's relative density. This will give you the mass of the metal. Mass of the metal = 0.02 grams × 19 = 0.38 grams.
Therefore, the mass of 20 cm³ of the metal when immersed in water would be 0.38 grams.
This question does not make any sense. The mass does not change when it is lifted by Archimedes.
the mass is
19 * 1 gram/cm^3 * 20 cm*3
= 380 grams
