Which equation shows the correct relationship between mass, force, and acceleration?
Serggg [28]

The acceleration on an object is proportional to the resultant force and inversely proportional to the mass of the object  

<h3>Further explanation  </h3>

Newton's 2nd law explains that the acceleration produced by <em>the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  </em>

∑F = m. a  

\large {\boxed {\bold {a = \frac {\sum F} {m}}}

F = force, N  

m = mass = kg  

a = acceleration due to gravity, m / s²  

Newton's equation shows that the greater the net force applied to an object, the greater the acceleration, conversely the greater the mass of the object, the smaller the object's acceleration.

You can use this principle to choose the available answer options, because the questions are not complete

Fluorine is diatomic element. What is the number of molecules in 10 moles<br> of fluorine gas?
sweet-ann [11.9K]
<h2>Answer:</h2>

6 × 10²⁴ molecules F₂

<h2>General Formulas and Concepts:</h2><h3><u>Chemistry</u></h3>

<u>Atomic Structure</u>

  • Using Dimensional Analysis
  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
<h3><u>Math</u></h3>

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right
<h2>Explanation:</h2>

<u>Step 1: Define</u>

10 mol F₂

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

<u />10 \ mol \ F_2(\frac{6.022 \cdot 10^{23} \ molecues \ F_2}{1 \ mol \ F_2} ) = 6.022 × 10²⁴ molecules F₂

<u>Step 4: Check</u>

<em>We are given 1 sig fig. Follow sig fig rules and round.</em>

6.022 × 10²⁴ molecules F₂ ≈ 6 × 10²⁴ molecules F₂
