Calculate the formula mass of barium bromate, Ba(BrO3)2, in atomic mass units (amu or u).
Look up the atomic mass of Ba and add it to 2* atomic mass of Br added to 6*atomic mass O. The total will be the mass in grams of a mole of barium bromate or the mass in amu of 1 molecule of barium bromate
Well, let me do some calculations while juggling a few equations in my head. Ba(BrO3)2, huh?
Alright, let's break it down. The formula has one barium atom (Ba), two bromate ions (BrO3), and each bromate ion consists of one bromine atom (Br) and three oxygen atoms (O3).
Now, let me consult my clownish periodic table... Ah, here we go! The atomic masses are approximately 137.3 u for Ba, 79.9 u for Br, and 16.0 u for O.
So, let's calculate:
(1 x 137.3 u) + (2 x [1 x 79.9 u + 3 x 16.0 u])
Calculating on my clown calculator... and... the total formula mass of barium bromate (Ba(BrO3)2) is approximately 445.2 atomic mass units (amu or u).
Voila! So, the atomic mass of Ba(BrO3)2 is like a clown juggling different elements.
To calculate the formula mass (also known as molar mass) of barium bromate, Ba(BrO3)2, we need to add up the atomic masses of all the elements in the compound.
The atomic mass of the elements can be found on the periodic table. Here are the atomic masses:
Ba: 137.33 amu
Br: 79.90 amu
O: 16.00 amu
Now, let's calculate the formula mass of Ba(BrO3)2 step-by-step:
1. Multiply the atomic mass of each element by the number of atoms in the compound:
For Ba: 1 atom × 137.33 amu = 137.33 amu
For Br: 2 atoms × 79.90 amu = 159.80 amu
For O: 6 atoms × 16.00 amu = 96.00 amu
2. Add up the calculated masses:
137.33 amu + 159.80 amu + 96.00 amu = 393.13 amu
Therefore, the formula mass of barium bromate, Ba(BrO3)2, is 393.13 amu.
To calculate the formula mass of a compound, you need to find the sum of the atomic masses of all the atoms in the formula. Here are the steps:
Step 1: Determine the atomic masses of each element.
The atomic mass of Ba (barium) can be found on the periodic table. It is approximately 137.33 amu.
The atomic mass of Br (bromine) is around 79.90 amu.
The atomic mass of O (oxygen) is approximately 16.00 amu.
Step 2: Determine the number of atoms for each element.
In the formula Ba(BrO3)2, there is 1 Ba atom, 2 Br atoms, and 6 O atoms.
Step 3: Calculate the formula mass by multiplying the atomic mass by the number of atoms for each element and summing them up.
Formula mass = (Atomic mass of Ba) + (Atomic mass of Br × Number of Br atoms) + (Atomic mass of O × Number of O atoms)
Formula mass = (137.33 amu) + (79.90 amu × 2) + (16.00 amu × 6)
Formula mass = 137.33 + 159.80 + 96.00
Formula mass = 393.13 amu
Therefore, the formula mass of barium bromate (Ba(BrO3)2) is 393.13 amu.
