0.540 g of bromine combine with 0.858 g of iodine to yield a compound X.Its % composition is
%Br = [0.540/(0.540+0.858)]*100 = ?
%I = done the same way.
Ah, bromine and iodine decided to play chemistry together! How delightful! Now, let's calculate the percent composition of compound X.
To do so, we need to find the mass of the compound formed. So, let's sum up the masses of bromine and iodine:
Mass of compound X = mass of bromine + mass of iodine
Mass of compound X = 0.540 g + 0.858 g
Mass of compound X = 1.398 g
Now, we can calculate the percent composition of bromine and iodine in compound X:
% composition of bromine = (mass of bromine / mass of compound X) x 100%
% composition of bromine = (0.540 g / 1.398 g) x 100% ≈ 38.68%
% composition of iodine = (mass of iodine / mass of compound X) x 100%
% composition of iodine = (0.858 g / 1.398 g) x 100% ≈ 61.32%
So, the % composition of compound X is approximately 38.68% bromine and 61.32% iodine. Keep in mind, though, that humor is my true area of expertise, not chemistry!
To determine the percent composition of compound X, we need to calculate the mass of bromine and iodine in the compound.
1. Calculate the molar mass of bromine (Br):
The molar mass of bromine is 79.904 g/mol.
2. Calculate the number of moles of bromine:
Moles of bromine = mass of bromine / molar mass of bromine
Moles of bromine = 0.540 g / 79.904 g/mol
3. Calculate the molar mass of iodine (I):
The molar mass of iodine is 126.904 g/mol.
4. Calculate the number of moles of iodine:
Moles of iodine = mass of iodine / molar mass of iodine
Moles of iodine = 0.858 g / 126.904 g/mol
5. Calculate the total mass of compound X:
Total mass of compound X = mass of bromine + mass of iodine
6. Calculate the percent composition of bromine:
Percent composition of bromine = (mass of bromine / total mass of compound X) * 100
7. Calculate the percent composition of iodine:
Percent composition of iodine = (mass of iodine / total mass of compound X) * 100
By following these steps, you can calculate the percent composition of compound X using the given masses of bromine and iodine.
To determine the percent composition of a compound, we need to know the masses of each element present in the compound.
Given:
Mass of bromine (Br) = 0.540 g
Mass of iodine (I) = 0.858 g
To calculate the percent composition, we first need to find the total mass of the compound X. We can do this by adding the mass of bromine and iodine:
Total mass of compound X = Mass of Br + Mass of I
Total mass of compound X = 0.540 g + 0.858 g
Total mass of compound X = 1.398 g
Now we can calculate the percent composition of each element in the compound:
Percent composition of bromine (Br) = (Mass of Br / Total mass of compound X) x 100%
Percent composition of bromine (Br) = (0.540 g / 1.398 g) x 100%
Percent composition of bromine (Br) = 0.386 x 100%
Percent composition of bromine (Br) = 38.6%
Percent composition of iodine (I) = (Mass of I / Total mass of compound X) x 100%
Percent composition of iodine (I) = (0.858 g / 1.398 g) x 100%
Percent composition of iodine (I) = 0.614 x 100%
Percent composition of iodine (I) = 61.4%
Therefore, compound X has a percent composition of 38.6% bromine (Br) and 61.4% iodine (I).
