Answer 1

Explanation:

Given Three pieces of silver have masses 2.3 kg ,41.15 kg and 30.19 kg. the total mass of correct significant figures is

• The pieces of silver have masses are 2.3 kg, 41.15 kg, and 30.19 kg
• Now we need to find the total mass
• So we need to convert gm to kg.
• So 2.3 kg  
• 41.15 gm = 41.15 / 1000 = 0.04115 kg
• 30.19 gm = 30.19 / 1000 = 0.03019 kg
• Now mass = 2.3 + 0.04115 + 0.03019
•                 = 2.37 kg
• Now total mass in correct number of significant figures = 2.4 kg.
