Final answer:
The weight of the astronaut on Mars would be 259 N.
Step-by-step explanation:
To calculate the new weight of the astronaut on Mars, we can use the formula Weight = mass x acceleration due to gravity.
The mass of the astronaut is given as 70 kg. The acceleration due to gravity on Mars is 3.7 N/kg.
Therefore, the weight of the astronaut on Mars would be:
Weight = 70 kg x 3.7 N/kg = 259 N
