Question

For a chemistry lab, you used 2 ounces of calcium sulfate, 2.5 pounds of copper, and 1 4 lb of nickel. What was the combined weight of your materials?

Answer 1

Answer:

Total weight = 266 ounce

Step-by-step explanation:

In this question we have to tell the combined weight of the materials in the same unit.

Weight of calcium sulfate = 2 ounces

Weight of copper = 2.5 pounds

Therefore weight of copper in ounces will be = 2.5× 16 ounces = 40 ounces

Weight of nickel = 14 pounds = 14 × 16 ounces = 224 ounces

So total weight = 2 + 40 + 224 = 266 ounces

Answer is 266 ounces is the combined weight of the materials.

Answer 2

16.625 pounds or 266 ounces
