Do objects weigh less on earth then on mercury

Objects weigh less on Mercury than they do on Earth. For example, if you weighed 68kg on Earth, you would weigh 25.7kg on Mercury.

In a scientific notation, you have to put a decimal right after the first number (unless it is a zero). How many times you move the decimal from its original spot determines the answer. (FYI: In a number like 196 the decimal point is 196.000<--here)

4.10000 (moved the decimal point 5 times, so the answer is --->) 
4.1 ×
