I assume you mean on Earth where the gravitation constant (g) is 9.8 m/s²
F = mg
300 = 9.8 * m
m = 300 / 9.8
m = 30.6 kg
If you are using a rounded value for g (10 m/s²), you will come up with a mass of 30 kg. This might be the intended answer if they want you to do it in your head.

OK, on what planet does she weigh 300 Newtons? It's a small, but important detail.

where? at earth?
weight = mass x g
g = gravitional acceleration = 10 m/s2 (at earth)
mass = 300/10 = 30 kilograms

weight = force.
F = ma
so weight = ma
300 N = m9.81m/s2
m = 300/9.81
mass = 30.58 kg

w = mg
(w is weight, m is mass, g is acceleration due to gravity (9.8m/s^2))
:. m = w/g
= 300 / 9.8
= 30.6 kg

if i take g=10m/s^2 for simplification then it's 30kgs
other wise taking 9.8m/s^2 will give 30.6kgs
