The moles of disodium edta used is calculated using the below formula

moles =molarity x volume in liters

molarity=0.050m
volume in liters = 22/1000=0.022 L

moles is therefore= 0.022 x0.050 =1.1 x10^-3 moles of disodium edta

How many moles of water as a gas can be formed 2.45 L

Alex17521 [72]

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 = $\frac{volume of gas}{22.4}$

Input the parameters and solve;

Number of moles of water = $\frac{2.45}{22.4}$ = 0.11mole

The number of moles of water found is 0.11mole
