Answer:
7.21 grams is the mass of methane
Explanation:
We may use the Ideal Gases Equation to solve this:
P. V = n. R. T
Let's determine the moles of Ar
18 g . 1 mol/ 39.9 g = 0.451 mol
In both situations, volume, temperature and pressure are the same so the moles of methane will also be the same as Argon's.
Let's convert the moles to mass of CH4.
0.451 mol . 16g/1mol = 7.21 grams
Answer:
.094 M
Explanation: 0.32molNaCl/ 3.4L = .094M
Among ¹⁴⁰₅₅Cs and ¹³³₅₅Cs, <u>¹³³₅₅Cs</u> is more stable.
<h3>Briefly explained</h3>
Let's review the criteria that are used to determine a stable isotope. A stable isotope will have more neutrons than protons with a neutron to proton ratio somewhere between one and 1.52 On the high atomic number, we're up to 152 at low atomic numbers were closer to one. More stable isotopes have an even number of protons. And neutrons.
And stable isotopes have their proton or neutron number equal to one of these magic numbers. So if we have season one, It has 85 Protons are start 85 neutrons And 55 protons. So we have a neutron to proton ratio of 155 for CCM 1 33. We have 78 neutrons and 55 protons for a neutron to proton ratio of 1.42. 155 is a little high for z equal to 55.
Both of these are also odd. So ¹⁴⁰₅₅Cs is the least stable. ¹³³₅₅Cs is the most stable.
