Calculate the number of moles in 1.8gram of h2o​

Chemistry
1 answer:
Rzqust [24]3 years ago
7 0

Answer:

~.1058 Moles

Explanation:

The formula for this question is the following.

1 mole of a compound/molar mass of the compound.

First we need to find the molar mass of H2O, which is the atomic mass on the periodic table. Hydrogen is 1.01, Oxygen is 16.00. Add those together to get the molar mass of the compound and you'll get an equation that looks like this.

1 mole of H2O/ 17.01 g/mol H2O

We now know that in 1 mole of H20 there is 17.01 g.

Take 1.8g and divide it by 17.01, you get your answer.

How many grams of carbon dioxide are produced from the combustion of 250.G of ethane, C3H8 in the reaction C3H8 +5O2 - 3CO2 +4H2
ludmilkaskok [199]

Answer:

750 g of CO₂

Explanation:

The balanced equation for the reaction is given below:

C₃H₈ + 5O₂ —> 3CO₂ + 4H₂O

Next, we shall determine the mass of C₃H₈ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:

Molar mass of C₃H₈ = (12×3) + (8×1)

= 36 + 8 = 44 g/mol

Mass of C₃H₈ from the balanced equation = 1 × 44 = 44 g

Molar mass of CO₂ = 12 + (16×2)

= 12 + 32 = 44 g/mol

Mass of CO₂ = 3 × 44 = 132 g

SUMMARY:

From the balanced equation above,

44 g of C₃H₈ reacted to produce 132 g of CO₂.

Finally, we shall determine the mass of CO₂ produced by the reaction of 250 g of C₃H₈. This can be obtained as follow:

From the balanced equation above,

44 g of C₃H₈ reacted to produce 132 g of CO₂.

Therefore, 250 g of C₃H₈ will react to produce = (250 × 132)/44 = 750 g of CO₂.

Thus, 750 g of CO₂ were obtained from the reaction.

Which are characteristics of a person who is nearsighted?
Mars2501 [29]

Answer: People that are usually nearsighted have lots of difficulty reading road signs from far distance, also have difficulty with seeing distant objects clearly, and this is obviously something dangerous for a person who has trouble with seeing from far. And the weird thing is, they might have that difficulty but in the other hand, they are able to see very well from close-up tasks such as reading a book or seeing the computer screen clearly. This disability is called "myopia".  In addition, people who are nearsighted also have difficulty seeing objects from far distance very blurry.   Farsightedness is the result of the visual image being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak.

I hope this helps answer your question! If you have options for this question, let me know k :) (Ask for help too)
