Bulk Modulus Problem, Help Please!?

Question

When water freezes, it expands about 9.00%. What would be the pressure increase inside your automobile engine block if the water in it froze? The bulk modulus of ice is 2.00 x 10^9 N/m^2.

My current work was...

P = (Bulk Modulus) x (Change in V)

P = (2 x 10^9) x (0.09)

P = 180000000

Is this right? If not, please show the correct method with work, thanks!

Answer 1

you are correct but you need to make it 1.80 X 10^8 because of the significant figures.
