Please help I’m timed You label another 100-ml beaker "#2", place it in a tared balance, and determine its mass. A portion of the unknown liquid is added to the beaker
and the mass of the liquid and the container is recorded.
mass of the empty beaker: 74.205 g
mass of the beaker with unknown liquid: 136.840 g
Using the Law of Conservation of Mass, what is the mass of the added liquid?

When determining the shape of a molecule, it is important to draw a lewis dot structure first in order to see the total number a. electrons within the moleculeb. bonding and unshared pairs around central atomc. unshared pair within the molecule( i really need it )

Arecipe calls for 1.2 cups of oil. how many liters of oil is this?

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
