The molecular weight of nitrous oxide (N₂O),known as laughing gas,is ________ amu (rounded to one decimal place).

Question

Quizplus · Accepted Answer

To calculate the molecular weight of nitrous oxide, we need to add up the atomic weights of all the atoms in the molecule. 
N: 1 atom x 14.01 amu = 14.01 amu 
O: 2 atoms x 15.99 amu = 31.98 amu 
Total molecular weight = 14.01 amu + 31.98 amu = 44.0 amu (rounded to one decimal place). Therefore, the best choice is C.
