Add or subtract the following measurement be sure each answer you enter contains this correct number of significant digits
5.90g-0.900g=?g
3.627g+1.1g=?g
3.707g-0.6g=?g
5.90g - 0.900g = 5.000g (Corrected to 3 significant digits)
3.627g + 1.1g = 4.73g (Corrected to 3 significant digits)
3.707g - 0.6g = 3.10g (Corrected to 3 significant digits)
To add or subtract measurements while preserving the correct number of significant digits, follow these steps:
1. Determine the measurement with the least number of decimal places. This will be the limiting factor in terms of the number of significant digits.
2. Perform the addition or subtraction operation.
3. Round the result to the same number of decimal places as the measurement with the least number of decimal places.
Let's apply these steps to the given calculations:
1. 5.90g - 0.900g = (subtract operation)
Since 0.900g has the least number of decimal places (3 decimal places), we need to round the result to 3 decimal places.
Substituting the values, we have:
5.90g - 0.900g = 5.000g (rounded to three decimal places)
2. 3.627g + 1.1g = (add operation)
In this case, 3.627g has the least number of decimal places (3 decimal places).
Substituting the values, we have:
3.627g + 1.1g = 4.727g (rounded to three decimal places)
3. 3.707g - 0.6g = (subtract operation)
Again, 0.6g has the least number of decimal places (1 decimal place).
Substituting the values, we have:
3.707g - 0.6g = 3.1g (rounded to one decimal place)
Therefore:
5.90g - 0.900g = 5.000g
3.627g + 1.1g = 4.727g
3.707g - 0.6g = 3.1g
