1. Nitrogen monoxide is oxidized in air to give brown nitrogen dioxide. Starting with 2.2mol NO, how many moles and how many grams of 02 are required for complete reaction? What mass of NO2,in grams, is produced? Please show the solution step by step. thanks

Answer 1

_Step 1:_
Balance the equation:
_ NO + _ O2 = _ NO2

2.2mol NO requires ___mol O2

_Step 2:_
Use the molar mass of O2 to determine the mass of that amount.
Using:
Molar mass of O2 is 31.99886 ± 0.00002 g/mol

_Step 3:_
Repeat steps one and two to determine the amoung of NO2 produced and its mass.

Using:
Molar mass of NO2 is 46.00558 ± 0.00003 g/mol
