Answer:</h3>
5.6 L
<h3>
Explanation:</h3>
We are given;
- Initial volume, V1 = 3.5 L
- Initial pressure, P1 = 0.8 atm
- Final pressure, P2 = 0.5 atm
We are required to calculate the final volume;
- According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.
- That is; P α 1/V
- Mathematically, P=k/V
- At two different pressure and volume;
P1V1 = P2V2
In this case;
Rearranging the formula;
V2 = P1V1 ÷ P2
= (0.8 atm × 3.5 L) ÷ 0.5 atm
= 5.6 L
Therefore, the resulting volume is 5.6 L
10% is normally how it works .
For example like 1,000 is the top the next level would be 100 then the next would be 10
Answer:
b) 3.000 mol S
Explanation:
using Avogadro's constant
1 mol = 6.02 × 10^23 atoms
we need to find the number of moles for 1.806 × 10^24
x = 1.806 × 10^24
putting it together we now have:
1 mol = 6.02 × 10^23 atoms
x = 1.806 × 10^24
cross multiply
6.02 × 10^23 x = 1.806 × 10^24
divide both sides by 6.02 × 10^23
x = (1.806 × 10^24) ÷ (6.02 × 10^23) = 3 mol
