Answer 2

Answer:

Explanation:

Find the percent by mass in which 41.0 g of NaCl is dissolved in 331 grams of water. Alcohol-based hand sanitizers clean hands by killing many types of disease- causing bacteria and viruses. How many mL of ethanol are contained in an 8.0- oz bottle of hand sanitizer that has & concentration of 629 (v/v) of ethanol? Note that (1 fl-oz = 29.6 mL)_ If 28.5 g of calcium hydroxide in Ca(OHJz is dissolved in enough water to make 185 g of solution, what is the percent by mass of Ca(OHJzin the solution? A wine contains 12% alcohol by volume. Calculate the volume (in mL) of alcohol in 350 ml of wine. 5. A 50 mL of 129 by mass-volume was used in an experiment: How many grams of solute does the solution contain? Calculate the mole fraction of sulfuric acid HzSO4 in 89 (wlw) aqueous HzSOa solution. Calculate the mole fraction of each component of a solution containing 65 g of ethanol € 2H 6O in 350 g of water. 24.0g of NaCl is dissolved in enough water to make .750 L of solution. a. What is the molarity (M) of the solution? How many moles of NaCl are contained in 0.0100 L of the above NaCl solution? What volume (L) of this NaCl solution would contain 0.200 moles of NaCl? Ammonia (NHs) and phosphoric acid solutions (HsPO4) are used to produce ammonium hydrogen phosphate (NHAJzHPOz fertilizer. What volume of 15.0 M NHzlaq) is needed to react with IO00 L of 13.5 M of HzPOa(aqi? 10.In an experiment; .01000 L sample of sulfuric acid solution reacts completely with 0.0160 L of 0.150 M potassium hydroxide Calculate the concentration of the sulfuric acid. Do not forget to balance the equation first. HzSOa(aq) KOHiaq) HzOw KzSOAlaq)
