A bug walking on the surface of a puddle is depending on HIGH SURFACE TENSION BECAUSE OF THE ATTRACTION BETWEEN WATER MOLECULES.
Water has a lot of interesting properties due to the hydrogen bonds that hold its molecules together. One of the interesting property of water is surface tension.
Surface tension refers to the property of the water surface, which enables it to resist an external force. The cohesive forces among the water molecules is responsible for the surface tension. The surface tension of water allow small animals such as insects to walk on water.
Answer:
25.3 g of KNO₃ contain 0.25 moles.
Explanation:
Given data:
Number of moles of KNO₃ = ?
Mass of KNO₃ = 25.3 g
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of KNO₃:
KNO₃ = 39 + 14+ 16×3
KNO₃ = 101 g/mol
Now we will put the values in formula.
Number of moles = 25.3 g/ 101 g/mol
Number of moles = 0.25 mol
Thus, 25.3 g of KNO₃ contain 0.25 moles.
9moIN2 :
The molar ratio between Nitrogen and ammonia is
1
:
3
, therefore, to produce 18 moles of ammonia, we will need
