Skim milk (fat free milk) is one of the best options to get enough calcium. Skim milk has approximately 306 milligrams of calcium per cup. The density of skim milk is 1.033 g/mL.
Answer the following questions, remember to show your work:
1) If you consume a quart of milk per week. How many mg of calcium will you take in a week? (Consider 2 an exact number in: 1 qt = 2 pt , 1 pt = 2 cups)
1a. Include the solution map with the corresponding equalities using three (3) steps map.
1b. Solve the problem.
2) Using ONLY the density as conversion factor method, calculate the grams of milk contained in 1 cup of milk. (Consider 8 in 1 cup = 8 oz an exact number)
2a. Include the solution map with the corresponding equalities using five (5) steps map.
2b. Solve the problem.

Pls! plant cells and animal cells were observed under a microscope. the characteristics of two cells are listed below. cell p: does not capture sunlight cell q: has cytoplasm but no chloroplast which statement about the two cells is correct? cell q also has a cell wall. cell q also has large vacuole. cell p also has a large vacuole. cell p also has a cell membrane.

Straightforward questions answered in the powerpoint slidesreaction: heating the starting materials under refluxwhat does it mean to heat under reflux? why do we choose water as the reflux solvent? what are boiling chips used for? why do we put a condenser on top of the reaction? why do we add heat and let the reaction stir for 30 minutes? why do we add sulfuric acid to the reaction after it cools as opposed to when it’s still hot? separation: filtration of precipitatewhy don’t we do an aqueous and organic extraction in the separatory funnel? why do you rinse the salicylic acid on the filter with ice cold water? purification: recrystallization of salicylic acid (no hot filtration needed)what is the difference in the amount of room temperature water vs. boiling water needed to dissolve the salicylic acid (assume a 1.2 gram yield of salicylic acid)? remember, in the lab if you need x ml of boiling water to dissolve a solid, then you should add a little more (definitely no more than 1.5 times the theoretical amount) to ensure it doesn’t recrystallize prematurely. analysis: melting point of salicylic acidwhat can you conclude if the melting point of the salicylic acid you just synthesized is 152-155oc and the 1: 1 mix of your product and “synthetic” salicylic acid is 151-154oc?

The tendency of water molecules to stick together is referred to as a) adhesion b) polarity c) cohesion d) transpiration e) evaporation
