To convert moles to grams, we need to use the molar mass of dinitrogen oxide (N20).
The molar mass of N20 is calculated by adding the atomic masses of nitrogen (N) and oxygen (O).
Molar mass of N: 14.01 g/mol
Molar mass of O: 16.00 g/mol
Molar mass of N20 = (2 * Molar mass of N) + Molar mass of O
= (2 * 14.01 g/mol) + 16.00 g/mol
= 28.02 g/mol + 16.00 g/mol
= 44.02 g/mol
Now, we can calculate the grams in 1.40 moles of dinitrogen oxide:
Grams = Moles * Molar mass
= 1.40 moles * 44.02 g/mol
= 61.636 g
Therefore, there are 61.636 grams in 1.40 moles of dinitrogen oxide.
Dinitrogen oxide (or nitrous oxide), N20, also known as laughing gas, is widely used as an anesthetic in dentistry.
