A new synthetic element has two isotopes. If the first isotope has a mass of 259.98 amu and a percent abundance of 43%, what is

Maurinko [17]

The sum of the percentage abundance of these two isotopes of the new synthetic element should be equal to 100. If we let x be the percent abundance of the second isotope, we have the equation, 43 + x = 100The value of x = 57

In a chemistry laboratory, a student filled a 10.0 L container with two (2) different gases. The

alexgriva [62]

Answer:

$P_N=1.33atm\\\\P_O=0.67atm$

$P_T=2.00 atm$

Explanation:

Hello.

In this case, the first step is to compute the moles of nitrogen and oxygen given their initial P, T and V conditions via the ideal gas equation:

$n_{N}=\frac{P_{N}V_{N}}{RT} =\frac{2.00atm*24.0L}{0.082\frac{atm*L}{mol*K}*273K}\\ \\n_{N}=2.144molN\\\\n_{O}=\frac{P_{O}V_{O}}{RT} =\frac{2.00atm*12.0L}{0.082\frac{atm*L}{mol*K}*273K}\\ \\n_{O}=1.072molO$

After that, since the total volume now, once the mixture is formed is the addition between the initial volumes (12.0 L + 24.0 L) is 36.0 L, the partial pressure of each gas turns out:

$P_N=\frac{2.144mol*0.082\frac{atm*L}{mol*K}*273K}{36.0L}\\\\P_N=1.33atm\\\\P_O=\frac{1.072mol*0.082\frac{atm*L}{mol*K}*273K}{36.0L}\\\\P_O=0.67atm$

Thus, the final total pressure is:

$P_T= P_N+P_O=1.33atm+0.67atm\\\\P_T=2.00 atm$

Best regards.
