Answer:

Moles of carbon dioxide are 1.57

Explanation:

Using ideal gas law, you can find moles of a gas with its pressure, temperature and volume, thus:

PV = nRT

PV/RT = n

Where P is pressure, V is volume (35.2L); R is gas constant (0.082atmL/molK); T is absolute temperature and n are moles

At STP, temperature is 273.15K and pressure is 1atm

Replacing:

1atm×35.2L / 0.082atmL/molK×273.15K = n

1.57 = n

Moles of carbon dioxide are 1.57

Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:

10 mol NH3 ( 6.022 x 10^23 molecules / 1 mol ) = 6.022x10^24 molecules NH3
