How many liters of water vapor are in 36.21 g?
Elden [556K]

Answer:

45.02 L.

Explanation:  

  • Firstly, we need to calculate the no. of moles of water vapor.
  • n = mass / molar mass = (36.21 g) / (18.0 g/mol) = 2.01 mol.
  • We can calculate the volume of knowing that 1.0 mole of a gas at STP occupies 22.4 L.

<em><u>Using cross multiplication:</u></em>

1.0 mole of CO occupies → 22.4 L.

2.01 mole of CO occupies → ??? L.

∴ The volume of water vapor in 36.21 g = (22.4 L)(2.01 mole) / (1.0 mole) = 45.02 L.

Find the no. of atoms present in 40g of nitrogen gas at STP?
nika2105 [10]

Answer:

8.60 * 10^{23} atoms N2

Explanation:

We want to convert grams to moles and then moles to atoms.

First, we convert grams of nitrogen gas (which is N2) to moles. To do so, we need the molar mass of N2, which is just 14.01 * 2 = 28.02 g.

40 g N2 * \frac{1 mol N2}{28.02 g N2} = 1.43 mol N2

Now, we need to convert moles to atoms by using Avogadro's number, which is 6.022*10^{23}:

1.43 mol N2 * \frac{6.022*10^{23} atoms N2 }{1 mol N2} = 8.60 * 10^{23} atoms N2

Thus, the answer is 8.60 * 10^{23} atoms N2.

16 Which two gases can not be broken down by chemical means?(1) CO and He (3) Xe and He
lyudmila [28]
The answer is (2) CO and NH3. The chemical reaction can only break down chemical bonds between atoms inside the molecule. The He and Xe is consists of one atom only, so they can not be broken down by chemical means.
