Answer:</h3>
5.0 × 10^21 atoms of sulfur
<h3>
Explanation:</h3>
We need to know that 1 mole of an element contains atoms equivalent to the Avogadro's number.
Therefore;
1 mole of an element = 6.022 × 10^23 atoms
Thus, 1 mole of sulfur = 6.022 × 10^23 atoms
But, molar mass of sulfur = 32.065 g/mol
This means;
32.065 g contain 6.022 × 10^23 atoms
Therefore, 2.66 g of Sulfur will contain;
= (2.66 g ÷ 32.065 g/mol) × 6.022 × 10^23 atoms
= 5.0 × 10^21 atoms
Answer:
Explanation:
<u>Given the following data;</u>
Initial volume = 400 mL
Final volume = 2000 mL
Initial pressure = 3 atm
To find the final pressure P2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;
C. It just seems right. And it doesn't day anything about atoms. That's guess.
The population will get low because the food we eat is animals which is species then the animals that eat that prey will die off because that might be there only prey....then if more species is gone there will be nothing left
I Hope this helped
