45 Gg = [? ]x10!?g<br> ]<br> =<br> ]
nlexa [21]

1. The coefficient (green) is 45

2. The exponent (yellow) is 9

<h3>Conversion scale</h3>

To convert from giga grams (Gg) to grams (g), the following coversion scale can be use:

1 Gg = 10⁹ g

With the above convesion scale, we can convert 45 Gg to g as follow

1 Gg = 10⁹ g

Therefore,

45 Gg = 45×10⁹ g

Thus, 45 Gg is equivalent to 45×10⁹ g. Hence, we can conclude as follow:

  • The coefficient (green) is 45
  • The exponent (yellow) is 9

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

<u>Step 1: Define</u>

50.0 mol H₂O

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

Avogadro's Number

<u>Step 3: Convert</u>

<u />\displaystyle 50.0 \ mol \ H_2O(\frac{6.022 \cdot 10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O} ) = 3.011 × 10²⁵ molecules H₂O

<u>Step 4: Check</u>

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

3.011 × 10²⁵ molecules H₂O ≈ 3.01 × 10²⁵ molecules H₂O

What is the equilibrium equation for the dissociation of formic acid in water? hcooh (aq) + h2o (l) ⇌ h3o+ (aq) + hcoo- (aq)?
Pani-rosa [81]
Formic acid when in water would dissociate into ions just like any acids. It would dissociate into the hydrogen ion and the formate ion. The equilibrium dissociation equation would be written as:

<span>HCOOH (aq) + H2O (l) ⇌ H+ (aq) + HCOO- (aq)

Formic acid is a weak acid which means that when in aqueous solution it does not completely dissociate into its corresponding ions. Only a certain amount that would be dissociated so in the solution there will be HCOOH, HCOO- and H+ molecules. It is also known as Methanoic acid and an important substance for the synthesis of a number of substances. It is naturally occurring in ants.</span>
