Question

1. read the triple beam balance below . what is the mass in grams? ______g
2. read the triple beam balance below . what is the mass in mg? (think: how many mg in 1g?) ______mg

Explanation:

Question 7

Step1: Identify each beam's value

• The top beam (hundreds place): The pointer is at 300 g.
• The middle beam (tens place): The pointer is at 50 g.
• The bottom beam (ones and tenths place): The pointer is at 6.3 g (since each small division is 0.1 g, and it's at 6.3).

Step2: Sum the values

Add the values from each beam: \( 300 + 50 + 6.3 = 356.3 \)

Step1: Recall gram to milligram conversion

We know that \( 1 \, \text{g} = 1000 \, \text{mg} \).

Step2: Convert the mass from g to mg

The mass in grams is \( 356.3 \, \text{g} \). To convert to milligrams, multiply by 1000: \( 356.3 \times 1000 = 356300 \)

Answer:

\( 356.3 \)
