How many moles of oxygen molecules are present in 112ml of co2 at NTP?​

Chemistry

dexar [7]3 years ago
7 0

In each mole of carbon dioxide there will be one mole of O₂.

Let us calculate the moles of carbon dioxide gas present first

The conditions are NTP it means , Temperature = 293 K and P = 1 atm

We will use ideal gas equation

PV= nRT

Where

P = Pressure of gas = 1 atm

V= 112mL=0.112L

R= gas constant =0.0821 L atm /mol K

n = moles = ?

Putting values

moles=\frac{PV}{RT}=\frac{1X0.112}{0.0821X293}

moles = 0.00466

Thus moles of carbon dioxide will be 0.00466

The moles of O₂ = 0.00466

Difference between---<br> soap and detergent
guapka [62]

Answer:

"Soaps are made from natural ingredients, such as plant oils (coconut, vegetable, palm, pine) or acids derived from animal fat. Detergents, on the other hand, are synthetic, man-made derivatives. While soap is limited in its applications, detergents can be formulated to include other ingredients for all sorts of cleaning purposes. Perhaps the most common and versatile of these ingredients are surfactants … surface active agents.

The main difference between soap and detergent is the ingredients. Soaps are made with biodegradable ingredients such as oils, lye and fats. ... Both clean clothes well, but detergents are more effective on stains and with brightening clothes. However, soap is kinder on the environment and skin. "

Hope this helps

A race car is driven by a professional driver at 99 . What is this speed in and ? 1 mile = 1.61 kilometers 1 hour = 60 minutes E
slavikrds [6]

Answer: The speed is equivalent to <u>159.39 kilometers per hour </u>or <u>2.65 kilometers per minute.</u>

Explanation:

Given, The speed of a race car = 99 miles/ hour

To convert the speed into  kilometers per hour and kilometers per minute

Since   1 mile = 1.61 kilometers

So, Speed of car = (99 ) x (1.61 )

= 159.39 kilometers per hour.

Also, 1 hour = 60 minutes

Then, Speed of car = (159.39) ÷60

= 2.6565≈2.65 kilometer per minute.

Hence, the speed is equivalent to <u>159.39 kilometers per hour </u>or <u>2.65 kilometers per minute.</u>
