1. The problem statement, all variables and given/known data

I only have a question on the calculation, so I won't even give the question...
My book says

(0.5877 \times 10^{-23} \:g) \times (6.022 \times 10^{-23} \: mol^{-1} )= 35.45 \: g \cdot mol^{-1}


According to my calculator (0.5877 \times 10^{-23} \:g) \times (6.022 \times 10^{-23} \: mol^{-1})= 3.545 \times 10^{-46} \: g \cdot mol^{-1}

How did they get rid of the 10^{-46} sign??

Thanks!

There is an error in the expression, should be 6.022x1023, not 6.022x10-23. This is the Avogadro's number.
