How would I solve this?

The ball's weight is mathematically given as
m=2.44*10^30
Question Parameters:
Q=1.6*10^{10}
E=15.0*10^{20}
Generally, the equation for the mass is mathematically given as
m=EQ/g
Therefore
m=1.6*10^{10}*15.0*10^{20}/9.81
m=2.44*10^30
In conclusion
The weight of the ball is
m=2.44*10^30
