Answer to Question #98062 in General Chemistry for Kriti

Question

Put the following instructions for weighing by difference in the correct order.


Calculate the mass of solid transferred.



Record mass of empty weighing boat



Place empty weighing boat on the analytical (4 d.p.) balance



Empty the solid into a beaker



Record the mass of the full weighing boat



Place the full weighing boat on the analytical (4 d.p.) balance



Place weighing boat on top-pan (2 d.p.) balance



Tare (zero) the top-pan (2 d.p.) balance



Add between 2.4 and 2.6 g of solid to the weighing boat. Remove the weighing boat from the balance while adding to avoid contamination.



Tare (zero) the analytical (4 d.p. balance)

Answer 1

You should know that many other balances are much more delicate than these and can be damaged easily if they are not used correctly. You will need instruction for each new kind of balance you work with.
