Answer:

1.2mol

Explanation:

Determine the g/mol of CO2

O - 16g/mol (based on my data booklet)

C - 12.01g/mol (based on my data booklet)

Then add these values up for the g/mol of CO2

16+16+12.01= 44.01g/mol

Then write out the formula

mol = mass/molar mass

n= m/M

n = 55/44.01

n= 1.24971597

and depending on what significant digits you need (based on info, ill do it to 2 terms)

n = 1.2 mol
