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 get lol? ?

Step-by-step explanation:

Givens

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,

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

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

the answer is 175.4379
