Question

Dr. Sanat was performing an experiment in his lab. He has three test tubes filled with a chemical each with a capacity of 50 mL. He poured all the chemicals into a large vessel above a burner as shown in the figure.


If the vessel is already filled with 100 mL chemical before the experiment, what will be the total amount of chemical in the vessel after the experiment?

• A. 0.25 L
• B. 0.2 L
• C. 1.50 L
• D. 0.28 L

Answer 1

The correct option is A 0.25 L

Here, we can see that Dr. Sanat was performing an experiment in which he was pouring chemicals from test tubes.

Total volume of chemical in test tubes = 50 mL × 3 = 150 mL

=> Amount of chemical in the vessel before the experiment = 100 mL

=> Total amount of chemical in the vessel = 100 + 150 = 250 mL

=> Total amount of chemical (in L) = $\frac{250}{1000}$ = 0.25 L {Since 1000 mL = 1 L}

Hence, the total amount of chemical in the vessel during Dr. Sanat’s experiment is 250 mL.
