Jeff used an equal arm balance to weigh a 4.312 g sample of sodium chloride. which of these measurements made by jeff is the most accurate? 4.1 g4.2g4.3g 4.5 g

Option B: 4.3

There are following rules for rounding off numbers:

1. If the rounding digit has digit less than 5 (1,2,3 and 4) to its right, all the digits on right side of the rounding digit will drop out.

2. If the rounding digit has digit equal and greater than 5 (5,6,7,8 and 9) to its right, one is added to the rounding digit.

Jeff has to weigh 4.312 g sample of NaCl. To round off the underline number 4.312, check for the digit right to it. It has 1, which is less than 5 thus according to the Rule 1, all the digits on right side of the rounding digit will drop out and the number gets rounded off to 4.3.

Therefore, 4.3 is most accurate measurement by Jeff.

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.
