Answer:
39.2 L at STP
Explanation:
Convert the grams to moles first by dividing 56.0 by the molar mass of O2 (32.0) then convert to volume by multiplying by 22.4.
= 39.2 L
Answer:
C. A stretch of raised land, often built to help control flooding and the flow of a river.
Explanation:

The volume (in mL) of methylergonovine the nurse should draw up in the syringeis is 0.25 mL
<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
With the concept of density, we can obtain the volume of methylergonovine. Details below
<h3>How to determine the volume </h3>
The following data were obtained from the question:
- Mass = 0.2 mg
- Density = 0.8 mg/mL
- Volume =?
Density = mass / volume
Cross multiply
Density × volume = mass
Divide both sides by density
Volume = mass / density
Volume = 0.2 / 0.8
Volume = 0.25 mL
