Answer: Formula: Mass = (Volume)(Density)
Iron Density = 7.87 g/cm^3
Volume of Iron = 55.2 cm^3
Mass=(V)(D)
Mass= (55.2 cm^3) x (7.87 g/cm^3)
Mass= 434,42 g

Answer:
2.41 × 10²⁰ atoms
Explanation:
Step 1: Given data
- Mass of a single molybdenum atom: 1.59 × 10⁻²² g
- Mass of the molybdenum sample: 38.3 mg
Step 2: Convert the mass of the sample to grams
We will use the relationship 1 g = 1,000 mg.
38.3 mg × (1 g/1,000 mg) = 0.0383 g
Step 3: Calculate the number of atoms in 0.0383 g of molybdenum
0.0383 g × (1 atom/1.59 × 10⁻²² g) = 2.41 × 10²⁰ atom
