An experimental mouse weighs about 4.41 x 10-2 lbs. what would the weight be in the si unit for mass?

The weight of the mouse in the SI unit would be 0.02 kg.

Mass is the unit which describe the quantity of matter in an object, the SI unit of mass is kilogram.

And conversion factor of one pound to one kg is

1 lb=0.4535 kg

Now the mass of the mouse in Si unit is calculated as

m=0.4535*4.41*10^ (-2)

=0.02 kg

Therefore the mass of the mouse in the SI unit is 0.02 kg.
