How many moles of xenon trioxide are present in 1. 69 grams of this compound.
Vadim26 [7]

Answer:

0.00944

Explanation:

Xenon mass number on the periodic table: 131.29

Oxygen mass number: 16.00

Add them to find the molar mass of xenon trioxide: 131.29+3(16) = 179.29g/mol

Convert this to moles

1.69g * \frac{mol}{179.29g} = 0.00944mol

If the mass ratio of nitrogen to hydrogen in ammonia is 4.7:1. if a sample of ammonia contains 10.0 gram of h, how many grams of
Tju [1.3M]

The amount, in grams, of N that the sample will contain will be 2.1 grams.

<h3>Stoichiometric mass ratio</h3>

According to the problem. the mass ratio of H and N in ammonia is 4.7:1.

In other words, every 4.7 grams of H in ammonia must have 1 gram of N.

Now, in a particular ammonia sample, 10 grams of H is present.

The amount of N present can be calculated from the standard mass ratio.

4.1 grams H = 1 gram N

10 grams H = x

4.1x = 1 x 10

        x = 10/4.1

             x = 2.1 grams

Thus, the mass of nitrogen in the ammonia sample will be 2.1 grams.

The equilibrium constant for the chemical equation is Kp = 5.23 at 191 °C. Calculate the value of the Kc for the reaction at 191
Lapatulllka [165]
To convert from Kp to Kc, you need this formula---> Kp= Kc (RT)^Δn, where Δn= gas moles of product- gas moles of reactants. since you did not give a reaction formula, I can't calculate Δn. but all once you find it out. just plug it. 

Kp= Kc (RT)^Δn------------------> Kc= Kp/[(RT)^Δn]
 Kp= 5.23
R= 0.0821
T= 191 C= 464 K
Δn= ?

Kc= 5.23/ (0.0821 x 464)^Δn= ???
