Answer:
6.3 atm
Explanation:
P2=T2P1/T1
Change C to K
We can check this by knowing that P and T at constant V have a proportional relationship; Hence, this is correct.
Answer:
B)
an atom of mercury has a different mass than an atom of copper.
Explanation:
Answer is: number is 0.14303691.
Carbon-13 (¹³C) is a stable isotope of carbon with mass number 13, it has six protons and seven neutrons.
Isotopes are chemical elements with same atomic number, but different mass number (different number of neutrons).
ω(¹³C) = 1.10% ÷ 100%.
ω(¹³C) = 0.0110; abundance of carbon-13 in nature.
m(¹³C) = 13.003355; the atomic mass of carbon-13.
ω(¹³C) · m(¹³C) = 0.0110 · 13.003355.
ω(¹³C) · m(¹³C) = 0.14303691.
