Convert 4.00 atm to mmHg
Ksivusya [100]

Answer:

3040 mmHg

Explanation:

Here

we have to convert 4.00 atm to mmHg

As we know that

The number of atm in 1 mmHg is 0.0013157895567935

Now there is 4.00 atm So, in mmHg it would be

And, according to this, the working is given below:

= 4 ÷ 0.0013157895567935

= 3,039.99

= 3040 mmHg

Hence, the last option is correct

And, the same is relevant and considered too

4NH3+5O2=4NO+6H20 if 32.5 grams of NH3 react with enough oxygen, how many grams of water should form?
Aneli [31]

51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.

<h3>How to find the Number of moles ?</h3>

To calculate the number of moles use the formula

Number of moles = \frac{\text{Given Mass}}{\text{Molar Mass}}

                              = \frac{32.5}{17}

                              = 1.9 mol

4NH₃ + 5O₂ → 4NO + 6H₂O

4 mol of NH₃ react with oxygen to given 6 mole of water.

So 1.9 mol of NH₃ produces = \frac{1.9}{4}\times 6

                                              = 2.85 mol of water

Mass of water = Molar Mass of water × Number of moles of water

                        = 18 × 2.85

                        = 51.3 gram

Thus from the above conclusion we can say that 51.3 gram of water should form if 32.5 g of NH₃ react with enough oxygen.
