Elaine needs 5.55g of sea salt. She has 4.0 L of water from the Atlantic Ocean. The density of this water is about 1.027g/mL. What volume of this water will provide her with the needed mass of sea salt?

Vinegar contains 5.00% acetic acid by mass and has a density of 1.01 g/mL. What mass(in grams) of acetic acid is present in 5.00 L of vinegar?

Assume the density of air at room temperature is 1.2 g/mL. A student is holding two balloons filled with gases: one balloon filled with hydrogen gas ( density=0.082 g/mL) and second balloon filled with carbondioxide gas (density=1.9 g/mL). predict what would happen if the student release both the balloons?

A chemist prepares a solution of nickel(II) chloride (NiCl₂) by measuring out 2.1 × 10² μmol of nickel(II) chloride into a 350. mL. volumetric flask and filling the flask to the mark with water. Calculate the concentration in μmol/L of the chemist's nickel(II) chloride solution. Round your answer to 2 significant digits. 0 μmol L x10

A glass of skim milk supplies 0.1 mg of iron and 8.1 g of protein. A quarter pound of lean meat provides 3.1 mg of iron and 21 g of protein. A person on a special diet is to have 3.8 mg of iron and 77.7 g of protein. How many glasses of skim milk and how many​ quarter-pound servings of meat will provide​ this?

Part A What is the density of the solid? p= Submit 17 ΑΣΦ Provide Feedback Request Answer www g/mL

A patient is treated with hydroxychloroquine for malaria. The drug is given based on the body mass of the patient. The dosage is 0.274 MG hydroxychloroquine/ 1.65 kg body mass. Calculate the amount (in g) of the drug that would be delivered to a 98.3 kg patient in each dose

A solution was created by dissolving 7.399 g of calcium chloride in 54.2 mL of water (d = 1.00 g/mL). What is the boiling point of this new solution? The ko for water is 0.52°C/m. The boiling point of pure water is 100.0°C. Round your answer to 2 decimal places.

You want to compare a patient's measured calcium ion concentration to the normal calcium ion concentration in blood serum.  The only range you can find is 4.5 - 5.5 mEq/L, but the blood results show a concentration of 0.22 mmol/dL.  Convert the measured calcium ion concentration from the blood results to mEq/L (to one decimal place). What are the units?
