Answer:

D) N2O5

Explanation:

The molar mass of a substance is defined as the mass of this substance in 1 mol. To solve this question we must find the molar mass of each option:

<em>Molar mass NO:</em>

1N = 14g/mol*1

1O = 16g/mol*1

14+16 = 30g/mol

<em>Molar mass NO2:</em>

1N = 14g/mol*1

2O = 16g/mol*2

14+32 = 46g/mol

<em>Molar mass N2O:</em>

2N = 14g/mol*2

1O = 16g/mol*1

28+16 = 44g/mol

<em>Molar mass N2O5:</em>

2N = 14g/mol*2

5O = 16g/mol*5

28+80 = 108g/mol

That means the compound with the greatest mass is:

<h3>D) N2O5</h3>

200 divided by 55 would equal 3.64.

I am dividing because to solve time would be distance/rate.
