What is the molarity of a solution prepared by diluting 30.0 mL of 1.20-M cuprous nitrate (CuNO3) to a final volume of 150.0 mL?

i used the formula M1xV1= M2xV2 

got an answer of 0.24 M CuNo3, but it's incorrect , not sure what i'm doing wrong.

    (30.0 mL) x (1.20 M) / (150.0 mL) = 0.240 M

    The answer should be in 3 significant digits. So try 0.240 M
