Question

how many moles of water are there in a cake containing 10^24 molecules of water?
Pa help po Thx :)​

Answer 1

Answer:

moles = No. of molecules / Avagadro Number

= 10²⁴ / 6 × 10²³

= 10 / 6

Moles of water = 1.66

Answer 2

Answer:

There are 6.022 x $10^{23$ moles of water in a cake containing $10^{24$ molecules of water.

Explanation:

From the above question,

They have given :

To calculate the range of molecules in one mole of water.

The quantity of molecules in one mole of water is  6.022 x $10^{23$.

Divide the range of molecules of water in the cake via the quantity of molecules in one mole of water.

$10^{24$ molecules of water ÷ 6.022 x $10^{23$  molecules of water

                                       = 6.022 x $10^{23$ moles of water.

The quantity of moles of water in a cake containing $10^{24$molecules of water can be calculated by way of dividing the quantity of molecules of water with the aid of Avogadro's wide variety (6.022 x $10^{23$).

This calculation offers us 6.022 x $10^{23$ moles of water, which is the equal quantity of water molecules that are current in one mole of water. This is a beneficial way to rapidly calculate the quantity of a substance in a given quantity of molecules.

The range of moles can be calculated with the aid of dividing the wide variety of molecules of a substance with the aid of Avogadro's variety (6.022 x $10^{23$).
