Answer:
0.11mole
Explanation:
Let us assume that the condition is at standard temperature and pressure(STP);
Given parameters:
Volume of water = 2.45L
Unknown:
Number of moles found in this volume of water = ?
Solution;
At STP;
Number of moles = ![\frac{volume of gas}{22.4}](https://tex.z-dn.net/?f=%5Cfrac%7Bvolume%20of%20gas%7D%7B22.4%7D)
Input the parameters and solve;
Number of moles of water =
= 0.11mole
The number of moles of water found is 0.11mole
