Answer :
Answer:
3.95 oz
General Formulas and Concepts:
Chemistry - Stoichiometry
- Using Dimensional Analysis
Explanation:
Step 1: Define
Apple iPhone = 112 g
Step 2: Identify Conversions
1 lb = 454 g
1 lb = 16 oz
Step 3: Convert
[tex]112 \ g(\frac{1 \ lb}{454 \ g} )(\frac{16 \ oz}{1 \ lb} )[/tex] = 3.94714 oz
Step 4: Check
We are given 3 sig figs. Follow sig fig rules and round.
3.94714 oz ≈ 3.95 oz
Final answer:
The weight of an Apple iPhone can be calculated by converting the mass from grams to pounds and then from pounds to ounces which results in approximately 3.94 ounces.
Explanation:
To find the weight of an Apple iPhone in ounces, we can use the conversion factors provided. Given that 1 pound (lb) is equal to 16 ounces (oz) and 1 pound (lb) is equivalent to 454 grams (g), we can convert the mass of the iPhone from grams to pounds and then from pounds to ounces.
First, convert the mass of the iPhone from grams to pounds:
112 g ÷ 454 g/lb = 0.246 lb
Next, convert the mass in pounds to ounces:
0.246 lb × 16 oz/lb = 3.9376 oz
Therefore, the weight of the Apple iPhone is approximately 3.94 ounces.
