Answer:
3189.07Pa
Explanation:
The conversion of 23.92mmH to Pa can be achieved in the following way:
760mmHg = 101325Pa
23.92mmHg = (23.92x101325)/760 = 3189.07Pa
Answer:
d= 14.007 amu
Explanation:
Abundance of N¹⁴ = 99.63%
Abundance of N¹⁵ = 0.37%
Atomic mass of N¹⁴ = 14.003 amu
Atomic mass of N¹⁵ = 15.000 amu
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (14.003 × 99.63)+(15.000× 0.37) /100
Average atomic mass = 1395.12 + 5.55 / 100
Average atomic mass = 1400.67/ 100
Average atomic mass = 14.007 amu.
Answer:
20 grams
Explanation:
40g= 300
x = 150
cross multiply, 40*150/300
6000/300= 20g
Answer:
3.01x10^23
Explanation:
In order to determine the amount of molecules, you have to use Avogadro's number which = 6.02x10^23. To calculate this, multiply the number of moles with Avogadro's number to get the above answer.
Hope this helps!
Answer:
Explanation:
The electronic configuration is defined as the setting or the arrangement of electrons in the shells of an atom. Generally, the noble gases do not react and thus show inertness. This property is due to 8 electrons in their outermost shell except for Helium. Bromine is a non-metal that has 35 electrons.
When Bromine atom gains an electron then becomes ion and called as bromide ion and thus bromide ion contains 36 electrons. Krypton is a noble gas that has 36 electrons and thus its electronic configuration is 
.
