Assuming all volume measurements are made at the same temperature and pressure, how many liters of water vapor can be produced w
maria [59]
For the reaction 2 K + F2 --> 2 KF,
consider K atomic wt. = 39
23.5 g of K = 0.603 moles, hence following the molar ratio of the balanced equation, 0.603 moles of potassium will use 0.3015 moles of F2. (number of moles, n = 0.3015)

Now, following the ideal gas equation, PV = nRT
P = 0.98 atm
V = unknown
n = 0.3015 moles
R = 82.057 cm^3 atm K^-1mole^-1 (unit of R chosen to match the units of other parameters; see the reference below)
T = 298 K
Solving for V,
V = (nRT)/P = (0.3015 mol * 82.057 cm^3 atm K^-1 mol^-1 * 298 K)/(0.98 atm)
solve it to get 7517.6 cm^3 as the volume of F2 = 7.5176 liters of F2 gas is needed.


2. Use the formula: volume1 * concentration 1 = volume 2 * concentration 2
where, volume 1 and concentration 1 are for solution 1 and volume 2 and solution 2 for solution 2.

Solution 1 = 12.3 M NaOH solution
Solution 2 = 1.2 M NaOH solution

<span> Solving for volume 1, volume 1 = (12.4 L * 1.2 M)/12.3 M = 0.1366 L  </span>

How many moles are in 6.5g of carbonate​
NikAS [45]

Answer:

Number of moles =  0.12 mol

Explanation:

Given data:

Mass of carbonate = 6.5 g

Moles of carbonate = ?

Solution:

Number of moles = mass / molar mass

Molar mass of carbonate = 60 g/mol

Now we will put the values in formula:

Number of moles = 6.5 g/ 60 g/mol

Number of moles = 0.12 mol
