1) yes, the gravity does influence weight. as the garvity changes the weight of the object changes respectively. The strength of gravity is indirectly proportional to the distance of the centre of the mass to the gravity. Taking and example lets try to understand the concept.
2) No, gravity does not influence mass. Mass is the measure of the amount of matter present in the object which signifies its weight.weight however on the other hand is determined by the gravity. Gravity infleunces all objects irrespective of their masses.
