Question

The American Heart Association recommends that healthy adults limit dietary cholesterol to no more than 300 mg per day. Convert this mass of cholesterol to ounces (1 oz =28.3459 g). Assume 300 mg has just one significant figure.

Answer 1

300 mg = 0.01 oz

Step-by-step explanation:

Given:

Mass of Cholesterol = 300 mg

To determine:

The mass in units of ounces (oz)

Calculation:

Unit conversions-

10³ mg = 1 g

28.3459 g = 1 oz

The mass of cholesterol in grams is:

=
`(300mg*1g)/(1000g) =0.3 g`

The mass in oz is:

=
`(0.3g* 1 oz)/(28.3459) =0.01058 oz`

When rounded to 1 sig fig, the mass would be = 0.01 oz
