8 0

Answer:

Identify the "given" information and what the problem is asking you to "find."

Given : Cl2O7

Find: % Composition (% Cl and %O)

List other known quantities.

Mass of Cl in 1 mol Cl2O7 , 2 Cl : 2 x 35.45 g = 70.90 g

Mass of O in 1 mol Cl2O7 , 7 O: 7 x 16.00 g = 112.00 g

Molar mass of Cl2O7 = 182.90 g/mol

An object has a density of 10.00 g/mL. If the object has a volume of<br> 25.00 ml, what is the mass?
SVEN [57.7K]

Answer:

The answer is

<h2>250 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of object = 25 mL

Density = 10 g/mL

The mass of the object is

mass = 25 × 10

We have the final answer as

<h3>250 g</h3>

Hope this helps you

How many water molecules (H20) can be produced from 6 molecules of hydrogen gas (white) reacting with 6 molecules of oxygen gas
Inga [223]

Answer:

A. 6 water molecules, hydrogen is limiting.

Explanation:

For a molecule of water, you need 2 hydrogen atoms and 1 oxygen atom. Therefore, if there is 6 molecules of hydrogen and 6 molecules of oxygen, there are 12 atoms of hydrogen and 12 atoms of oxygen. You need 2 of hydrogen so you will divide 12 by 2. 12-2=6. You need only 1 atom of oxygen so it will stay as 12. The limiting reactant is hydrogen because there are only 6 while there are 6 atoms of oxygen remaining. There will only be 6 water molecules formed due to the insufficient amount of hydrogen.
