Will give brainliest To verify the previous experiment, the chemistry student carried out the next experiment and recorded the data for you in the following Data Table.

Directions: Place 100 mL of filtered, saturated PbCl2 in a 150 mL beaker and put it under a dryer to evaporate the water. Record the necessary data in the Data Table.

Complete the Data Table.

Since the data allows it, you should use 3 significant digits for all your answers.

Molecular weight of PbCl2 = 278 g/mole

Mass of beaker + PbCl2 = 62.19 g

Mass of beaker = 57.77 g

Mass of PbCl2 per 100 mL =
___g

Moles PbCl2 per 100 mL =
___
[Pb+2] based upon this investigation =
___M

[Cl-] based upon this investigation =
___M

This is close to our answer of 0.34 M above. The difference may be due to experimental error and to rounding numbers off because we were limited to 2 significant digits in the first part of this experiment. This illustrates the importance of using care with our procedures in the laboratory and to record instrument readings to as many significant digits as possible.
