Answer:
the total mass of the 250 objects is 1.3 kilograms.
Explanation:
To find the total mass of the 250 objects, we need to multiply the mass of each object by the number of objects:
Total mass = mass per object x number of objects
The mass per object is given as 5.2x10^-3 kg, and the number of objects is 250. So, we can calculate the total mass as follows:
Total mass = 5.2x10^-3 kg x 250
Total mass = 1.3 kg
