PV=nRT, n=(PV)/(RT)
(1.30)(3.46)=(n)(.0821)(274.27)
n=.199755 moles

Answer : The number of moles of gas present in container are, 0.1997 mole

Explanation :

Using ideal gas equation :

PV=nRT

where,

n = number of moles of gas  = ?

P = pressure of the gas = 1.30 atm

T = temperature of the gas = 274.27 K

R = gas constant = 0.0821 Latm/moleK

V = volume of gas = 3.46 L

Now put all the given values in the above equation, we get the moles of gas.

(1.30atm)\times (3.46L)=n\times (0.0821L.atm/mole.K)\times (274.27K)

n=0.1997mole

Therefore, the number of moles of gas present in container are, 0.1997 mole

How many moles of NaCl are present in 2.50 L of a 0.070 M solution?
posledela

Given :

Volume of NaCl solution 2.5 L .

Molarity of NaCl solution is 0.070 M .

To Find :

How many moles are present in the solution.

Solution :

Let, n be the number of moles.

We know, molarity is given by :

M = \dfrac{n}{V(in\ L)}

So,

n = M \times V\\\\n = 0.070\times 2.5 \\\\n = 0.175\ moles

Therefore, number of moles of NaCl is 0.175 moles.

Is kp or kc larger (both at 300 k) for the reaction 2 nh3(g) ⇀↽ n2(g) + 3 h2(g) ? 1. they are both the same. 2. kc is larger. 3.
fgiga [73]
The equation is 2 NH3 (g) ⇀↽ N2 (g) + 3 H2 (g) 
Difference in the number of moles delta n = ((3 + 1) - 2) = 4 - 2 = 2 
We have an equation Kp= Kc (R x T) ^ (delta n); R is constant and T = 300 K 
Kp / Kc = (R x T) ^2 Based on the temperature value (300 K), we can conclude that Kp is Larger.
