Q82E - Chemistry (OpenStax)

Question

Question: To prepare for a laboratory period, a student lab assistant needs 125g of a compound. A bottle containing ¼ 1b is available. Did the student have enough of the compound?

Step-by-Step Solution

Answer

No, they did not have enough of the compound.

Step 1: Determining why the student did not have enough of the compound

1lb = 453.59g

So, 

\(\frac{1}{4}lb = \left( {\frac{1}{4}} \right) \times 453.59g = 113.40g\)

The student needs 125g of the compound. Therefore the available bottle is not enough for him.
