Question:
Weigh out some salt (sodium chloride) following the two methods described below.
Method 1:
a.) zero the balance.
b.) Weigh and record the mass of a 50-mL beaker.
c.) Remove the beaker from the balance and transfer two small scoops of salt to it.
d.) Re-zero the balance.
e.)Weigh and record the mass of the beaker and salt.
f.) Determine the mass of salt in the beaker.
Method 2:
a.) place a 100-mL beaker on the balance and zero the balance using the tare (zero) function.
b.) Remove the beaker from the balance. Do not re-zero the balance.
c.) transfer two small scoops of salt to it.
d.) Place the beaker back on the balance and record the mass of salt in the beaker.
