Answer:
Explanation:
Hello,
In this case, we employ the combined ideal gas law in order to understand the volume-gas-pressure behavior as shown below:
Hence, solving for the final pressure P2, we obtain (do not forget temperature must be absolute):
Best regards.
1 mole of CH4 results to 2 moles of H2O.
If 8.5 liters are to be produced, then (1CH4/2H20)*(8.5L h2o) = 4.25L CH4
Answer:39.8375
Explanation:
The mole for the equation is 1:1
Then the molar mass of KCl is 74.5g
Molar mass of k is 39
74.5g of KCl gives 39g of k
76.10g of KCl gives xg of k
X= 76.10×39/74.5
X= 2967.9/7
X= 39.8375
Creo que la respuesta es <span>Iones positivos y una nube de electrones. </span>
<span>Abundance of each isotope = 0.1900 x100 = 0.001900
</span><span>0.2500 = 0.002500
</span><span>88.43 = 0.8843
</span>11.13 = 0.1113
Atomic mass of the element = (<span>135.90714 x 0.001900</span>) + (<span>137.90599 x 0.002500</span>) + (<span>139.90543 x 0.8843</span>) + (<span>141.90924 x 0.1113</span>)
= 0.258223566 + 0.344764975 + 123.718371749 + 15.794498412
= 140.1 amu is the atomic mass of the element
