What is the molecular formula of a compound if its emprical formula is NO2 and its molar mass is 138.02 g/mole
Ratling [72]

Answer:

N₃O₆  

Step-by-step explanation:

Data:

EF = NO₂

MM = 138.02 g/mol

Calculations:

EF Mass = (14.01 + 32.00) u

EF Mass = 46.01 u

The molecular formula is an integral multiple of the empirical formula.

MF = (EF)ₙ

  n = MF Mass/EF Mass  

  n = 138.02 u/46.01 u  

  n = 3.000 ≈3

MF = (NO₂)₃

MF = N₃O₆

What kinds of scientific investigations involve making observations?
rodikova [14]
<span>1. Coherence Theory (Theory of Coherence)

Based on this theory, a knowledge considered to be true if the knowledge kehoren with the knowledge that exists and has been proven to be true. In the study of mathematics this is usually called the deductive nature.

2. Correspondence Theory (Theory of corespondence)

Based on this theory, a knowledge considered to be true if the knowledge of having a relationship with a reality that is true. This theory is based on the empirical fact that knowledge is true if there are facts that support that is true knowledge. Thus the truth here is based on inductive inference.

3. Pragmatic Theory (Theory of Pragmatism)

According to this theory, knowledge is said to be true if the knowledge is seen practically completely or have properties that true practicality. Followers of this theory argue that knowledge is true if it has keguanaan practical<span>.</span></span>

What is the mass of the light bulb and paperclips together? a. 250.1 g b. 246.0 g c. 251.0 g d. 205.10 g
ololo11 [35]

251.0 is the correct mass  of the light bulb and paperclips together.

<h3>What is mass ? </h3>

Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of an object's gravitational pull to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit.

For a body, mass is constant. Mass can be calculated using the formula: mass = volume density. A mass's weight is a measurement of the gravitational force at work on it. The kilogram is the SI unit of mass.

The mass of the substance will therefore be calculated as follows: MASS OF A SUBSTANCE = VOLUME DENSITY.

So finally we can say that the mass of the light bulb and paperclips together is 250.1g.

<span>At a depth of 34 feet the diver experiences 2 atmospheres of pressure. At a depth of 68 feet the diver is experiencing 3 atmospheres. At a depth of 102 feet the diver is experiencing 4 atmospheres of pressure. At one atmosphere of pressure the body is mildy compressed. As the diver descends the divers body will undergo increased compression instead of being squashed.</span>
