HELPPPP !!! oxygen calculation to find neutrons
Tcecarenko [31]

Answer:

Oxygen has 8 neutrons

Explanation:

We know that cause the atomic number says how many protons does the element has, so in this case is eight, and in the mass number, we have the number of protons+neutrons, in this case is 16. Then, as we know that oxygen has eight protons with the atomic number, we would do 16-8 protons= 8 neutrons.

Check: Atomic number is 16= 8 protons + 8 neutrons

the hcp ordered 0.2 mg of methylergonovine, and the vial contains 0.8 mg/ml. how many ml of methylergonovine should the nurse dr
iogann1982 [59]

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
