A balloon has a volume of 292 mL and contains 0.0201 mol of CO2. What mass of N2 must be added to expand the balloon to 357 mL? (Assume constant temperature and pressure.)

Not sure how to go about this. Am I on the right path, is it correct so far?

V1 = V2

n1 n2

292 = 357

.0201 n2

40.69 mol then convert to grams? How?
