The following procedure from the lab worksheet has been performed for you to capture the required data.
Use the data provided to calculate the unknowns.
1. Support the meter stick at the center of gravity. Hang the unknown weight at the 70-cm mark as rx, and balance with suitable known weight (as m1) on the other side (as r1) of the fulcrum.
2. Weigh the unknown mass on the balance to get the true value. The true value of the unknown weight is 375 grams.
3. Calculate the Experimental Value of the Unknown Weight=?
HINT: rxmx = r1m1
4.
Calculate the Percentage of Error using the following relationship=?
Use the True Value for the Unknown Weight and the Experimental Value you calculated for the Unknown Weight from the third procedure.
Percentage of ErrorUnknown Weight = 
=?
| r1 | rx | m1 |  τ1 |
 τx |
| 30.5cm | 20 cm | 250 grams | 0.747 N.m | 0.74 N.m |
Please, help me.

I need help with lab this week. I have posted theory and procedures to the lab. The questions with ????????? are the ones I need help with. Please Help!! Thank you Theory Density is defined as mass per unit volume that has a metric unit of kg per cubic meter. Grams per cubic centimeter i.e. g/cm3 actually is widely used as the unit of density. The densities for objects with regular shapes are easily to be determined. For objects with...

4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value. Explain your answer in clear and correct English. 16 LABORATORY EXPERIMENTS IN GENERAL CHEMISTRY ed in question 4...
