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
Explanation:
The Gas Law Apparatus is a high-quality demonstrator of the relationship between pressure, volume and temperature of a gas. The pressure gauge shows how pressure affects volume and vice versa. A digital thermometer displays the temperature.
Answer:
=8 atoms
Explanation:
In (NH4)2C2O4 there are four moles of Hydrogen in the compound (NH4), but there two molecules of (NH4) in this compound. That's what the 2 in (NH4)2 means, so multiply 4 x 2 = 8.

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
