Question

how many miles of nf3 are present in a sample that contains 5.03 miles of fluorine atoms? please do the math

Answer 1

Answer:

We know that the given compound NF3

contains 1 mol of nitrogen and 3 mol of fluorine atoms

Step 1: calculation of moles of nf3

let x be the mole of nf3

then 3x = 5.03 moles [ because nf3 contains 3 fluorine atoms]

=>x=1.677 moles

so nf3 moles present = 1.677 moles in a sample that contains 5.03 moles of fluorine atoms
