An experimental procedure says to accurately weigh approximately 1 g of substance on analytical balance. Which of the following measurements are
consistent with these instructions? Select all that apply.
1.0456 g
1.0 g
0.9811g
1 g
1.01g
O 0.99

1.0456 g and 0.9811g

Explanation:

The measurements that are consistent with the approximate 1 g instruction would be 1.0456 g and 0.9811g.

Analytical balance generally weighs to an accuracy of 4 decimal places. Hence, every other option that is short of being in 4 decimal places is incorrect.

Also, 1.0456 g and 0.9811g when approximated to the nearest whole number give 1 g.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
