You have a solution that is 18.5 % (v/v) methyl alcohol. If the bottle contains 2.15 L of solution, what is the volume (V) in milliliters of methyl alcohol?

How would you prepare 350 mL of a 1:20 glucose solution? Write your answer with two digits past the decimal point.  (Important - Trailing zeroes count as digits - (e.g. 12.00 counts as two digits past the decimal point). I would weigh out  ? g of glucose and add water to  ? mL the answer is 2.801 M?

The EPA's secondary standards for contaminants that may cause cosmetic or aesthetic effects in drinking water suggest an upper limit of 250 mg/L for chloride ion. If 4.19×104 liters of water in a storage tank contains 4.20 grams of Cl-, what is the contaminant level in ppm? in ppb? Is this level acceptable based on EPA guidelines?

You need to make 30 mL of a 5 M Glucose solution.  How many grams of glucose would you dissolve in 30 mL of water?  (Give your answer with one place after the decimal point: example: 4.6) Use the information below for your calculations: Glucose: C6H12O6 Carbon: 6 12C Hydrogen: 1 1H Oxygen: 8 16O

Too much manganese in drinking water can cause the following undesirable effects: black to brown color; black staining; bitter metallic taste . The EPA's Secondary Maximum Contaminant Level for manganese in drinking water is5.00×10-2 mg/L.(1) If 1.52×104 liters of water in a storage tank contains 1.08 grams of Mn , what is the contaminant level in ppm? ppm      Assume that the density of the impure water is 1.00 g/mL.(2) Is this level acceptable based on EPA guidelines?

How many milliliters of a 0.900%0.900% (m/v) normal saline solution can be prepared from 3.003.00 g of sodium chloride, NaClNaCl? Note that mass is not technically the same as weight, but the abbreviation % (w/v) is often used interchangeably with % (m/v).

The minimum level of mercury levels in water considered safe is 1 part per billion (ppb) by weight. Ifyou did an analysis and found that the concentration was 0.59 parts per billion. What quantity of mercuryin grams was present in 8.52 L of the water, the density of which is 0.998 g/ml? (1 ppb Hg = 1 ng Hg per1 g water)

Calculate the freezing point of a solution of 367.4 g of ethylene glycol (C,H,O,, 62.067 g/mol) dissolved in 547.9 g of water. K = 1.86°C/m for water. Enter your temperature to one decimal place. Answer:

Vinegar is a solution of acetic acid in water. If a 225 mL bottle of distilled vinegar contains 19.8 mL of acetic acid, what is the volume percent (v/v) of the solution?

An aqueous solution of ammonium sulfate, (NH₂)2SO4, contains 2.04 grams of ammonil sulfate and 17.7 grams of water. What is the weight/weight percent of ammonium sulfate in the solution? Weight/weight percent=1 %
