What is the mass of 11.8 moles of water?

uysha [10]

First, find how many grams are in 1 mole of water.

For a hydrogen atom, there is about 1 gram per mole. For an oxygen atom, there are about 16 grams per mole.

In H2O, there are two hydrogen atoms and one oxygen atom. This means there are 18 grams in one mole of water. Multiply the mass in one mole by your number of moles.

18 x 11.8 = 212.4 grams

You have 212.4 grams of water.

What is the oxidation state of an individual carbon atom in caco3?

Marizza181 [45]

Answer:

The oxidation state of the carbon is +4.

Explanation:

Calcium is in group 2 of the periodic table, therefore, its oxidation state is +2.

The oxidation state of the oxygen is -2.

As the compound is neutral, the sum of the oxidation states of all atoms must be 0.

Oxidation State Ca + Oxidation State C + (Oxidation State O)×3 = 0

+2 + x + (-2)×3 = 0

2 + x - 6 = 0

x = 6 -2

x = 4

Hence, the oxidation state of the carbon is +4.

General Formulas and Concepts:

Atomic Structure

Reading a Periodic Table
Moles
Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

Stoichiometry

Using Dimensional Analysis

Explanation:

Step 1: Define

[Given] 2.8 × 10²⁴ atoms Si

[Solve] moles Si

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

[DA] Set up: $\displaystyle 2.8 \cdot 10^{24} \ atoms \ Si(\frac{1 \ mol \ Si}{6.022 \cdot 10^{23} \ atoms \ Si})$
[DA] Divide [Cancel like units]: $\displaystyle 4.64962 \ mol \ Si$

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

4.64962 mol Si ≈ 4.6 mol Si
