Question

Aluminum and tin are both metals.The standard atomic weight for aluminum is 26.98.The standard atomic weight for tin is 118.71.by rounding to the nearest one,Estimate the difference between the standard atomic weights for these two metals.(CAN I PLEASE GET HELP LOL??

Answer 1

Rounded weight for aluminum - 27
Rounded weight for tin - 119

119
27
-___
92

92 is your estimated difference

Answer 2

The difference between these weights is 92, rounded to the nearest unit.

Explanation:

Givens

• The standard atomic weight for aluminum is 26.98.
• The standard atomic weight for tin is 118.71.

Now, we need to find the difference between these two, but we need to round them to the nearest one, that is, to the nearest unit.

So,

`26.98 \approx 27`

`118.71 \approx 119`

Remember, when you want to round, you need to look the following digit. In this case, we want to round to the nearest one, and its following digit is the tenth digit. SO, in the first number this digit is 9, that means we can round the units 6, to the next digit. The same rule is applied to the second number.

Next, we subtract both numbers

`119-27 = 92`

Therefore, the difference between these weights is 92, rounded to the nearest unit.
