what is the molar mass of no2?\n1 mol n = 14.01 g n\n1 mol o = 16.00 g o\n1 mol no2 = ? g no2\nround your answer to two decimal places.
Answer
Explanation:
Step1: Identify nitrogen and oxygen amounts
$NO_2$ has 1 N atom and 2 O atoms.
Step2: Calculate molar - mass contribution of N
The molar mass of N is 14.01 g/mol. For 1 N atom in $NO_2$, the contribution is 14.01 g.
Step3: Calculate molar - mass contribution of O
The molar mass of O is 16.00 g/mol. For 2 O atoms in $NO_2$, the contribution is $2\times16.00 = 32.00$ g.
Step4: Calculate molar mass of $NO_2$
Add the contributions of N and O. $14.01+32.00 = 46.01$ g/mol.
Answer:
46.01
