First work out the moles
So do 36g / 80 (80 is bromine's relative Atomic Mass number)
You have 0.45 M
Then, do 0.45 * 6.02*10^23
You get 2.7*10^23, which is your answer

What is the average mass of two atoms for beryllium?
The average mass of two atoms of beryllium is approximately 8.00 atomic mass units (amu).
How many grams are in 0.02 moles of beryllium iodide moles of beryllium iodide?
To find the number of grams in 0.02 moles of beryllium iodide (BeI2), you would first calculate the molar mass of BeI2, which is 262.83 g/mol. Then, you would multiply the molar mass by the number of moles: 0.02 moles * 262.83 g/mol = 5.26 grams of beryllium iodide.
How many hydrogen atoms are in 360 grams of water?
There are 4.8 x 10^24 hydrogen atoms in 360 grams of water. This is calculated by using Avogadro's number to convert the mass of water to moles, and then using the chemical formula of water (H2O) to determine the number of hydrogen atoms present in 1 mole of water.
How many atoms are in 175 g of calcium?
To find the number of atoms in 175 g of calcium, we need to first calculate the number of moles of calcium using its atomic mass (40.08 g/mol). Then, we can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. Finally, multiply the number of moles by Avogadro's number to get the total number of atoms in 175 g of calcium.
What mass of He contains the same number of atoms as 5.0 g Kr?
To find the mass of He containing the same number of atoms as 5.0 g Kr, we need to use the fact that atoms are indivisible entities. First, determine the number of atoms in 5.0 g Kr using the molar mass of Kr. Then, calculate the mass of He containing the same number of atoms by dividing the atomic mass of He by Avogadro's number and scaling it up to match the number of Kr atoms.
What is the average mass of two atoms for beryllium?
The average mass of two atoms of beryllium is approximately 8.00 atomic mass units (amu).
If you have g of beryllium how many moles is this equivalent to?
The formula is: number of moles = g Be/9,012.
