How many oxygen atoms are in 25 g of oxygen?

Chemistry
1 answer:
shutvik [7]2 years ago

Answer:

Explanation:

Carbon Dioxide-CO2

To get molecules, we must convert grams to moles and moles to atoms using Avogadro's number.

Molar mass of CO2=

C:12.0g+O:16.0gx2=44.0g CO2

25.0g CO2 | 1 mol CO2 | 6.02x10 23 molecules CO2

= 3.42x10 23 molecules CO2

1 | 44.0g CO2 | 1 mol CO2

Now to get the number of oxygen atoms.

Since there are 3 atoms in CO2 and 2 of them are oxygen, we will divide by 3 (1.14x10 23) and multiply by 2 (2.28 x10 23)

So the number of oxygen atoms in 25.0 grams of CO2 is 2.28x10 23 or 228 000 000 000 000 000 000 000

5 advantages of storing oil underground in salt dome?
jasenka [17]

Answer:

Salt domes storage has advantages in cost, security, environmental risk, and maintenance. Salt formations offer the lowest cost, most environmentally secure way to store crude oil for long periods of time. Stockpiling oil in artificially-created caverns deep within the rock-hard salt costs historically about $3.50 per barrel in capital costs. Storing oil in above ground tanks, by comparison, can cost $15 to $18 per barrel - or at least five times the expense. Also, because the salt caverns are 2,000-4,000 feet below the surface, geologic pressures will sea; any crack that develops in the salt formation, assuring that no crude oil leaks from the cavern. An added benefit is the natural temperature differential between the top of the caverns and the bottom - a distance of around 2,000 feet; the temperature differential keeps the crude oil continuously circulating in the caverns, giving the oil a consistent quality.

In a chemical formula such as C6H12O6 and H2O, what do you call the little numbers below the normal line of text.
Morgarella [4.7K]

These are called subscript number.

That is the number below the normal line of test are called subscript number.

This number indicate the indicate the number of atoms of the element present in the chemical formula.

In both of these C₆H₁₂O₆ and H₂O, the number written below the line of the text are called subscript numbers.
