A person has a mass of 70.0 kg on Earth, what would their mass be on the Moon,
which has 1/6 the gravity of Earth?
A. more than on the Earth
B. less than on the Earth
C. the same as on Earth

B. Less than on the Earth

The moon has 1/6th the gravity, which is less.

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b
