The volume (in dL) of the piece of iron having a mass of 3.92 kg is 4.99 dL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to determine the volume of the iron</h3>
From the question given above, the following data were obtained:
- Mass of iron = 3.92 kg = 3.92 × 1000 = 3920 g
- Density of iron = 7.86 g/cm³
- Volume of iron =?
Density = mass / volume
Thus,
Volume = mass / density
Volume of iron = 3920 / 7.86
Volume of iron = 498.7277 cm³
Divide by 100 to express in dL
Volume of iron = 498.7277 / 100
Volume of iron = 4.99 dL
Thus, the volume of the iron is 4.99 dL

There's 34 quarters in 85 dimes.
If you divide 10 by 2 you get 5, every 2 quarters is 5 dimes.
Answer:
12.2329 atm
Explanation:
Applying
PV = nRT.................... Equation 1
Make P the subject of the equation
P = (n/V)RT................ Equation 2
Where P = Osmotic pressure, (n/V) = Molarity of urea, T = Temperature, R = molar gas constant.
From the question,
Given: (n/V) = 0.5 M, T = 25°C = (273+25) = 298 K, R = 0.0821 Latm/mol.K
Substitute these values into equation 2
P = (0.5)(298)(0.0821)
P = 12.2329 atm
