Aye you have the same class as me bruh I need help on some chemistry qustions
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 = 
Input the parameters and solve;
Number of moles of water =
= 0.11mole
The number of moles of water found is 0.11mole
Decomposed organic matter ,mud,silt ,and sand
The formula C2H4 can be classified as both a molecular formula
and an empirical formula. The answer is number 4.
