The beginning of the Pre Cambrian is known as the Hadean eon. The planet was just born, and it was very very hot, and in fact molten. There were a lot of volcanic activities, and because of the way the solar system was created, there were still a lot of collisions between different bodies

How many atoms of sodium are in 3.80 mol of sodium, Na?
vova2212 [387]

Answer:

2.29 × 10²⁴ atoms Na

Explanation:

Step 1: Define

Avagadro's Number: 6.02 × 10²³ atoms, molecules, formula units, etc.

Step 2: Stoichiometry

3.80 \hspace{3} mol \hspace{3} Na(\frac{6.02(10)^{23} \hspace{3} atoms \hspace{3} Na}{1 \hspace{3} mol \hspace{3} Na} ) = 2.2876 × 10²⁴ atoms Na

Step 3: Simplify

We have 3 sig figs.

2.2876 × 10²⁴ atoms Na ≈ 2.29 × 10²⁴ atoms Na

A sample of gas under pressure of 882kPa has a volume of 312cm3. The pressure is increased to 948kPa. What volume will the gas o
levacccp [35]

Answer:

V₂ = 290.3 cm³

Explanation:

Given data:

Initial pressure = 882 KPa

Initial volume = 312 cm³

Final pressure = 948 KPa

Final volume = ?

Solution:

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

882 KPa× 312 cm³ = 948 KPa × V₂

V₂ = 882 KPa× 312 cm³/ 948 KPa

V₂ = 290.3 cm³
