A slice of Swiss cheese contains 41 mg of sodium.

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?

$mass=\frac{41 mg*0.001 g}{1 mg}$

mass= 0.041 grams

41 mg equals 0.041 grams.

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?

$mass=\frac{41 mg*3.5274*10^{-5}ounces }{1 mg}$

mass= 1.4462*10 ⁻³ ounces= 0.0014462 ounces

41 mg equals 0.0014462 ounces

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?

$mass=\frac{41 mg*2.20462*10^{-6}pounds }{1 mg}$
