Answer: 62.173%
explanation:
equation for percentage mass of an element in a compound = (Mass of element in compound / mass of the whole compound ) × 100%
% mass = (46.63÷75.00) × 100
= 0.62173 × 100
= 62.173%
Answer:
33.0 L
Explanation:
Step 1: Given data
- Initial volume of the balloon (V₁): 30.0 L
- Initial temperature (T₁): 25.00 °C
- Final volume of the balloon (V₂): ?
- Final temperature (T₂): 55.00 °C
Step 2: Convert the temperatures to the Kelvin scale
We will use the following expression.
K = °C + 273.15
T₁: K = 25.00°C + 273.15 = 298.15 K
T₂: K = 55.00°C + 273.15 = 328.15 K
Step 3: Calculate the final volume of the balloon
If we assume ideal behavior, we can calculate the final volume of the balloon using Charles' law.
V₁/T₁ = V₂/T₂
V₂ = V₁ × T₂/T₁
V₂ = 30.0 L × 328.15 K/298.15 K = 33.0 L
Answer:
We smell hot food from distance because of the diffusion process. Diffusion is the spreading out and intermixing of particles From one substance into another substance due to the movement of particles.
