Calcium chloride is 36.0% calcium by mass. A 5.00g sample of calcium chloride contains what mass of chlorine?
Wouldn't that be (1-0.36)*5.00 g = ?
Calcium chloride is 36.0% calcium by mass. A 5.00g sample of calcium chloride contains what mass of chlorine?
To find the mass of chlorine in a sample of calcium chloride, you need to use the information that calcium chloride is 36.0% calcium by mass.
Here's how you can calculate it step by step:
Step 1: Determine the mass of calcium in the sample:
The sample weighs 5.00g, and calcium chloride is 36.0% calcium. Therefore, the mass of calcium in the sample is:
Mass of calcium = 5.00g x (36.0/100) = 1.80g
Step 2: Calculate the mass of chlorine in the sample:
The sum of the masses of calcium and chlorine in the sample should be equal to the total mass of calcium chloride. So, you subtract the mass of calcium from the total mass to find the mass of chlorine:
Mass of chlorine = Total mass of calcium chloride - Mass of calcium
Mass of chlorine = 5.00g - 1.80g = 3.20g
Therefore, a 5.00g sample of calcium chloride contains 3.20g of chlorine.
