A sealed, expandable container is initially at 2.000 L and 25°C. To what temperature must it be changed to have a volume of 6.00

balandron [24]

Answer:

The new temperature is 894 K or 621 °C

Explanation:

Step 1: Data given

Initial volume of the container = 2.000L

Initial temperature = 25.0 °C = 298 K

Volume increased to 6.00 L

Step 2: Calculate the new temperature

V1/T1 = V2/T2

⇒with V1 = the initial volume = 2.00L

⇒with T1 = the initial temperature = 25 °C = 298 K

⇒with V2 = the increased volume 6.00 L

⇒with T2 = the new temperature

2.00 L / 298 K = 6.00 L / T2

T2 = 894 K = 621 °C

The new temperature is 894 K or 621 °C

Answer: The average atomic mass of nitrogen is 14.0066 amu

Explanation:

Mass of isotope N-14 = 14.00307 amu

% abundance of isotope N-14= 99.64% = $\frac{99.64}{100}$

Mass of isotope N-13 = 15.0001 amu

% abundance of isotope N-13= (0.36)% = $\frac{0.36}{100}$

Formula used for average atomic mass of an element :

$\text{ Average atomic mass of an element}=\sum(\text{atomic mass of an isotopes}\times {{\text { fractional abundance}})$

$A=\sum[(14.00307)\times \frac{99.64}{100})+(15.0001)\times \frac{0.36}{100}]]$

$A=14.0066amu$

Therefore, the average atomic mass of nitrogen is 14.0066 amu
