Answer:

<em>The three gases, in the three identical containers, will all have the same number of molecules</em>

Explanation:

If these three gases (Helium He, Neon Ne, and Oxygen O_{2}) are all contained in separate identical containers with the same volume. And they are all stored at the same temperature, and pressure. Then, they'll all contain the same number of molecules. This is in line with Avogadro's law which states that "Equal volume of all gases, at the same temperature and pressure, have the same number of molecules."

Potassium-40 has a half-life of 1.277 mc013-1.jpg 109 years. After 1.022 mc013-2.jpg1010 years, how much potassium-40 will remai
olchik [2.2K]
The correct answer is approximately 1.95g. First, take (1.022*10^10)/(1.277*10^9). This is the same as time elapsed/half-life. This gives you 8, which is the number of half lives. Then multiply mass (500.3g) by (1/2)^8, resulting in 1.95g, which is the answer.

How many carbon atoms are present in 3.900 x 10-4 mol of carbon? Give your answer in scientific notation. x 10 (select) A
AnnyKZ [126]

<u>Answer:</u> The number of atoms of carbon present in given number of moles are 2.350\times 10^{20}

<u>Explanation:</u>

We are given:

Number of moles of carbon = 3.900\times 10^{-4}mol

According to mole concept:

1 mole of an element contains 6.022\times 10^{23} number of atoms.

So, 3.900\times 10^{-4}mol of carbon will contain = 3.900\times 10^{-4}\times 6.022\times 10^{23}=2.350\times 10^{20} number of atoms.

Hence, the number of atoms of carbon present in given number of moles are 2.350\times 10^{20}
