What is the maximum capacity for a class A balance?

the minimum weight is 120 mg the maximum weight is 120 g
Balances that weigh loads of more than 648 mg.
Super sensitive balances that weigh up to 120 mg.
Balances used for weighing large quantities.

The correct answer is: the minimum weight is 120 mg the maximum weight is 120 g

A class A balance refers to a type of analytical balance commonly used for measuring small masses with high precision. It is designed with a single-pan weighing mechanism and an internal calibration system to ensure accuracy. None of the other options provide a specific maximum weight capacity for a class A balance. Option B mentions a minimum weight of 648 mg, which is not relevant to the question. Option C mentions "super sensitive balances" which may not always refer to a class A balance. Option D mentions balancing for large quantities, which is also not relevant to the question about maximum capacity. Therefore, option A is the correct answer stating the maximum weight capacity of a class A balance as 120 g.
