Question
How many moles in 4.47 g of CaBr2?
Answer to 4 decimal points.
MW(CaBr2) = 199.88 g/mol
Solution
The number of moles of a substance can be calculated using the formula:
Number of moles = mass of substance (in grams) / molar mass (in g/mol)
Given: Mass of CaBr2 = 4.47 g Molar mass of CaBr2 = 199.88 g/mol
Step 1: Substitute the given values into the formula:
Number of moles = 4.47 g / 199.88 g/mol
Step 2: Perform the division to find the number of moles:
Number of moles = 0.0224 moles
So, there are 0.0224 moles in 4.47 g of CaBr2.
