You have a beaker with 25 mL of water in it How many grams of HCl would you need to add to your beaker to get a 0.5 M NaCl solution?
If a 150 mL glass beaker is filled to the brim with ethyl alcohol at a temperature of 8.20°C, how much will overflow (in mL) when the alcohol's temperature reaches the room temperature of 21.0°C? (Assume the beaker is initially at room temperature.) How much less water (in mL) would overflow under the same conditions?
6.52 grams of sodium hydrogen carbonate is weighed into a 150 ml beaker and dissolved in 100 ml of deionized water. The solution is then quantitatively transfer to a 250.0 mL volumetric flask and filled to the line with deionized water. What is the molarity of hydrogen carbonate in the volumetric flask?
A beaker contains 0.50 moles of potassium bromide dissolved to a total volume of 600.0 mL. How many moles of potassium bromide are in the beaker if 600.0 mL of water is added to the flask?
A beaker contains 44.9 mL of chloroform (CHCl3), density is 1.48 g/mL). Determine how many molecules of chloroform are in the beaker.
6. (20 pts) You have a beaker containing 100 mL of water. The initial temperature of the water is 20°C. (Note: Onc ml = 1 cm'). 2. You place a piece of copper into the beakct containing. When you do, the water level increases to 110.5 m... What is the mass of the copper in grams? b. If the temperature of the water increases to 35°C, how much heat (in calories) did the copper add to the water? c. You...
tration : Use a small beaker. I00-mL or 150-ml beaker and fill about ½ full of water. Cut a small piece of potassium metal, about the size of a small pea, place on a paper towel and quickly wipe off the mineral oil. Drop the small piece of metal into the Phenolphthalein may be added to indicate the formation of a basic solution. The may be lit. gas Hazard: Do not allow the potassium metal to be exposed to air...
