The empirical formula of the compound is C. NiF₂.
<em>Step 1</em>. Calculate the <em>moles of each element</em>
The empirical formula is the simplest whole-number ratio of atoms in a compound.
The ratio of atoms is the same as the ratio of moles.
So, our job is to calculate the molar ratio of Ni to F.
Moles of Ni = 9.11 g Ni × (1 mol Ni /(58.69 g Ni) = 0.1552 mol Ni
Moles of F = 5.89 g F × (1 mol F/19.00 g F) = 0.3100 mol F
<em>Step 2</em>. Calculate the <em>molar ratio</em> of the elements
Divide each number by the smallest number of moles
Ni:F = 0.1552:0.3100 = 1:1.997 ≈ 1:2
<em>Step 3</em>: Write the <em>empirical formula</em>
EF = NiF₂
When the temperature is cold, barely any of the liquid rises, so most of it is at the bottom.
When the temperature is hot, the liquid rises up, so the liquid is distributed about evenly across the thermometer's tube.
The new volume of a gas at STP that occupies 16L of space is 27.43L.
<h3>HOW TO CALCULATE VOLUME?</h3>
The volume of a given gas can be calculated using the following expression:
P1V1/T1 = P2V2/T2
Where;
- P1 = initial pressure
- P2 = final pressure
- V1 = initial volume
- V2 = final volume
- T1 = initial temperature
- T2 = final temperature
1 × 16/273 = 2.6 × V2/468
16/273 = 2.6V2/468
0.0586 × 468 = 2.6V2
V2 = 27.43
Therefore, the new volume of a gas at STP that occupies 16L of space is 27.43L.
