Question 17: Choose the correct answer: A box of Robecvan balances contains the following weights: 1mg; 10mg; 20 mg; 50 mg; 100 mg; 200 mg; 500 mg and 1g
Measuring the mass of an object with a Robovan balance is a way of comparing the mass of the object to be weighed with the mass of the sample weight.
Sample weights: 1mg; 10mg; 20 mg; 50 mg; 100 mg; 200 mg; 500 mg and 1g = 1000mg
So the DM of the balance will be the sample weight with the smallest mass and equal to 1mg .
GHD is the sum of the sample weights:
1 + 10 + 20 + 50 + 100 + 200 + 500 + 1000 = 1881 mg
The answer to choose is: GET
