Question

PLEASE HELP!!!
A student mixed two clear liquids together in a beaker and a solid precipitate formed. His data is shown below:
Liquid reactant A: 10 g
Liquid reactant B: 17 g
Beaker+Solid product: 32 g

What is the mass of the beaker?
a. 5 g
b. 10 g
c. 15 g
d. 17 g
e. 32 g

Answer 1

This might be right. Im not quite sure. This is what my 5th grade science teacher told me. 'Look at the 2 LR's and add them together. Then look at the total amount which is 32. When you add the 2 LR's you get 17. So subtract 17 from 32 and you get 15. So: C:15 is your answer." (LR's stands for liquid reactants)

10+17=17

Total amount is 32

32-17=15

15 is you mass

Hope this Helps
