The answer is:
the molarity = 50 moles/liters
The explanation:
when the molarity is = the number of moles / volume per liters.
and when the number of moles =2.5 moles
and the volume per liters = 0.05 L
so by substitution:
the molarity = 2.5moles/0.05L
= 50 moles /L

Answer;
4.5 m³
Solution:
The statement says that two blocks are present on a lid of a container with volume of 9 m³. The mass of lid is equal to the mass of two blocks. It means that initially there are four blocks (or four atm pressure) upon 9 m³ volume.
After that four more blocks are placed on the lid. Means the pressure is increased from 4 atm to 8 atm (2 atm of lid, 2 atm of old blocks, 4 atm of new four blocks).
So, Data generated is,
P₁ = 4 atm
V₁ = 9 m³
P₂ = 8 atm
V₂ = ?
According to Boyle's Law,
P₁ V₁ = P₂ V₂
Solving for V₂,
V₂ = P₁ V₁ / P₂
Putting values,
V₂ = (4 atm × 9 m³) ÷ 8 atm
V₂ = 4.5 m³
Answer:
38.1 L
Explanation:
Data given:
initial volume V1 of a gas = 3 L
initial Temperature T1 of a gas = 21 °C
convert Temperature to Kelvin
T1 = °C +273
T1 = 21°C + 273 = 294 K
final Temperature T2 of a gas = 100°C
convert Temperature to Kelvin
T2 = °C +273
T2 = 100°C + 273 = 373 K
final Volume V2 of a gas = ?
Solution:
This problem will be solved by using Charles' law equation at constant pressure.
The formula used
V1 / T1 = V2 / T2
As we have to find out Volume, so rearrange the above equation
V2 = V1 x T2 / T1
Put value from the data given
V2 = 3 L x 373 K / 294 K
V2 = 38.1 L
So the final Volume of a gas = 38.1 L
