The molar volume of a gas at stp, in liters, is . you can use the molar volume to convert 2 mol of any gas to l. you can also use the molar volume to convert 11.2 l of any gas to mol. avogadro’s law tells you that 1.2 l of o2(g) and 1.2 l of no2(g) are of moles of gas.

Let us consider the following points

a) The volume of one mole of an ideal gas at STP (273.15 K and 1 atm) is 22.4 L.

b) the number of moles of in any given volume of gas can be calculated as:

Solutions:

1) The molar volume of a gas at STP, in liters, is 22.4 L.

2) You can use the molar volume to convert 2 mol of any gas to 44.8 L

Volume = moles X 22.4L

Volume = 2 X 22.4 = 44.8L

3) You can also use the molar volume to convert 11.2 L of any gas to 0.5 mol.

As mentioned above

4)  Avogadro’s law tells you that 1.2 L of O2(g) and 1.2 L of NO2(g) are ______-numbers of moles of gas.

The moles of oxygen will be:

The moles of nitrogen dioxide will be:

Total moles = 0.0536+0.0536 = 0.1072 moles

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

a electronegativity decreases beacuse the size of nucleus is bigger.
