Answer:
a. 41 mg equals 0.041 grams.
b. 41 mg equals 0.0014462 ounces
c. 41 mg equals 9.039*10⁻⁵ pounds
Explanation:
You know that a slice of Swiss cheese contains 41 mg of sodium.
a. What is this mass in grams?
Knowing that 1 mg = 10⁻³ g, you can apply the following rule of three: if 1 mg equals 10⁻³ g or 0.001 grams, 41 mg will be equivalent to how much mass in g?

mass= 0.041 grams
<u><em>
41 mg equals 0.041 grams.</em></u>
b. What is this mass in ounces?
Knowing that 1 mg = 3.5274 * 10⁻⁵ ounces, you can apply the following rule of three: if 1 mg equals 3.5274 * 10⁻⁵ ounces, 41 mg will be equivalent to how much mass in ounces?

mass= 1.4462*10 ⁻³ ounces= 0.0014462 ounces
<u><em>41 mg equals 0.0014462 ounces</em></u>
c. What is this mass in pounds?
Knowing that 1 mg = 2.20462 * 10⁻⁶ pounds, you can apply the following rule of three: if 1 mg equals 2.20462 * 10⁻⁶ pounds, 41 mg will be equivalent to how much mass in pounds?

mass= 9.039*10⁻⁵ pounds
<u><em>41 mg equals 9.039*10⁻⁵ pounds</em></u>

Answer:
6.28 L
Explanation:
Given data:
Volume of NO₂ = ?
Mass of NO₂ = 12.9 g
Temperature and pressure = ?
Solution:
First of all we will calculate the number of moles of gas.
Number of moles = mass/molar mass
Number of moles = 12.9 g/ 46 g/mol
Number of moles = 0.28 mol
At standard temperature and pressure 1 mole of gas occupy 22.4 L volume.
Thus,
0.28 mol × 22.4 L/1 mol
6.27 L ≅ 6.28 L
