Answer:
The weight of chemical A to the nearest gram is 11 g
Step-by-step explanation:
we know that
To Round a number
a) Decide which is the last digit to keep
b) Leave it the same if the next digit is less than [tex]5[/tex] (this is called rounding down)
c) But increase it by [tex]1[/tex] if the next digit is [tex]5[/tex] or more (this is called rounding up)
In this problem we have
[tex]11.256\ g[/tex]
We want to keep the digit [tex]1[/tex]
The next digit is 2 which is less than [tex]5[/tex], so no change is needed to [tex]1[/tex]
therefore
The weight of chemical A to the nearest gram is 11 g
