NO 10 newtons is approximately 100grams so ten times.

No, but under normal conditions it is quite close. The weight of an object in Newtons is equal to the mass in kilograms x the acceleration under gravity. Since nominal gravitational acceleration at nominal sea-level is 9.812 m/s/s, one kilogram (1,000 grams) has a weight of 9.812 Newtons under these conditions. Therefore 100 grams would have a weight of 0.9812 Newton, quite close to the 1 Newton required for the statement to be true.
And by the way, 'J Clarkson' has got his decimal point in the wrong place; 10 Newtons is the weight of approximately 1019 grams of mass, i.e. just over 1 Kg, not 100 grams.
I hope this helps, but please feel free to drop me a line if you'd like me to go into greater detail on any part of this.

The sentence as specified does not make sense because mass and weight(force) have different units. Assuming that the question is poorly phrased and they are assuming an acceleration then it becomes
Force = Mass x Acceleration
or
Force/Mass = Acceleration
To convert mass in grams to mass in Kg you need to divide by 1000. So mass in grams = 100 x weight in newtons is saying that the mass in Kg = 0,1 x weight in newtons so we can substitute Fx0.1 for M and get
F/(0.1*F) = A
A bit of algebra gives A=10m/s/s so the statement is only true if the mass is experiencing an acceleration of 10m/s/s. This is only a few percent different to the gravitational acceleration at the surface of the Earth so I think the answer to the question is probably intended to be yes although it is shamefully poorly specified.

Weight = mass x acceleration due to gravity and g is 9.8 m/sec^2
1 newton is that force acting on a mass of 1 kg and producing an acceleration of 1 m/sec^2.
So, weight of m kg will be m Newtons.
So, the statement that m is 100 times the W is wrong.

Mass and force are differrent things , but very loosely a mass or weight of 100 grams will excert a force of one Newton in a downward direction due to gravity. This is a special case but very loosely you are right.

On earth, 1kg weighs approximately 9.81 newtons.
So 1 newton is the weight of 1000/9.81 grams = 101.9 grams.
The statement is therefore a fair approximation, but not exact.

No, Weight = Mass x Gravitational Field strength.
on Earth, g = 9.81,
so, Weight (on Earth) = mass*9.81
So the statement you have above is false :-)
