Answer: 0,4278g of F and 0,4191g of Fe
Explanation: it's possible to calculate the mass of each element by multiplying the percentage (decimal) of the element by the mass of the compound.
For Fluorine (F)
0,847g * 0,5051 = 0,4278g of F
For iron (Fe)
0,847 * 0,4949 = 0,4191g of Fe
This is determined because even when the compound is decomposed, due to conservative law of mass, the decomposition process do not affect the amount of matter, so the mass of the elements remain even if they are separated from the original molecule.
At the end, the sum of the elements masses should be the total mass of the compound.
Answer:
1.06L = V₂
Explanation:
Charle's Law states that the volume of a gas is directly proportional to the absolute temperature when pressure remains constant.
The equation is:
V₁T₂ = V₂T₁
<em>Where V is volume and T absolute temperature of 1, initial state and 2, final state of the gas.</em>
V₁ = 1.83L
T₂ = -100°C + 273.15 = 173.15K
V₂ = ?
T₁ = 27°C + 273.15 = 300.15K
V₁T₂ = V₂T₁
1.83L*173.15K = V₂*300.15K
<h3>1.06L = V₂</h3>
He could go at any of the first 3 times because he won't get back if he goes on the last. We need more information to help answer it.
