In order to determine the mass of a substance given the volume, we require the density. The density of iron is 7.87 grams/cm³
Now,
Density = mass / volume
Mass = density * volume
Mass = 7.87 * 4.6
36.2 grams of iron are present in the cube
Its arbitrary. It was developed on the greek phoenetic system and never reallybwas explained.

<h3>What is a tetraphosphorus decoxide?</h3>
Tetraphosphorus decoxide, () is a non-metal oxide that gives acidic property when dissolved in water.
The name phosphorus decoxide can be interpreted as 4 phosphorus (P) atoms (‘Tetra’), bonds with 10 oxygen (O) atoms (‘Dec’) in a molecule. besides that, it is also known as phosphorus pentoxide.
It can be prepared by heating pure phosphorus with oxygen in blast furnace.

It is used as a dehydrating agent due to its week van der Waals dispersion forces. Thus, owing to give exothermic reaction when dissolved in watermore precisely, it is a white crystalline anhydrous (without water molecule) solid.
In granular form it can be also used as desiccant as well.

You can detect salt in water without tasting by measuring the density of the water. Place a glass of spring water and a glass of the suspected salt water on a balance scale and the heavier one contains salt. Other ways to test for salt in water is to put a drop of water on the end of a nail and place in a gas flame. If the water contains salt, the flame will turn a yellow/orange color.
