A50 ml volumetric flask is calibrated to the and will hold exactly when filled to the calibration line: 0.01 ml, 100.00 ml 0.01 ml, 50.00 ml 0.01 ml. 50.000 ml 0.01 ml, 50.0 ml 0.1 ml, 50.00 ml 0.1 ml, 50.0 ml 0.1 ml, 50 ml

A 50  mL volumetric flask is calibrated to the 0.01 mL and will hold exactly 50.00 mL when filled to calibration line.

Every volumetric flask is calibrated with 0.01 mL so that when the liquid is filled till the calibration line the flask should hold 50.00 mL fluid in it. It gives precise and accurate measurements for the experiments. Calibration is a must for every glassware which ensures less experimental errors.

it is a solid

explanation:

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.
