Photosynthesis is literally the most important thing to the ecosystem, and in short is the source of all chemical energy (the kind the organisms use) in the ecosystem. ... This is why plants that perform photosynthesis are known as Producers, because they produce all of the original chemical energy in the ecosystem.

How many moles are in 3.45g of KCI ?

artcher [175]

<h3>Answer:</h3>

0.0463 mol KCl

<h3>General Formulas and Concepts:</h3>

<u>Math</u>

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

<u>Chemistry</u>

<u>Atomic Structure</u>

Reading a Periodic Table
Using Dimensional Analysis

<h3>Explanation:</h3>

<u>Step 1: Define</u>

3.45 g KCl

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

Molar Mass of K - 39.10 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of KCl - 39.10 + 35.45 = 74.55 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 3.45 \ g \ KCl(\frac{1 \ mol \ KCl}{74.55 \ g \ KCl})$
Multiply/Divide: $\displaystyle 0.046278 \ mol \ KCl$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

0.046278 mol KCl ≈ 0.0463 mol KCl
