Kelly prepares a cup of juice by mixing juice powder and 0.3kg of hot water at 68 degrees celcius. Find the minimum amount of ice at 0 degrees celcius that should be added to the juice in order to cool the juice to 15 degrees celcius. ( give c (juice) = 4000 J kg^-1 c^-1 )

4000 x 0.3 x ( 68-15 ) = Energy lost by juice

63600 = Energy lost by juice

Energy lost = energy gained.

so 334000 x m + 2260000 x 15 x m = 63600

34234000m = 63600

m=0.001857802kg

now this is a multiple choice question and options are as follows:

A 0.16kg

B 0.19kg

C 0.53kg

D 1.00kg

My answer is clearly wrong, so can someone tell me how to do this.
