If you have 0.96 M AgNO_3 solution, how many liters of the solution would contain 6.44 moles AgNO_3? How many moles of CH_3CH_2OH are contained in 657 mL of 0.0788 M CH_3CH_2OH solution? How much volume would 51.5 kg of ethyl alcohol occupy if 4.11 mole...
(i) Number of moles of carbon atoms. (ii) Number of moles of hydrogen atoms. (iii) Number of molecules of ethane. View Solution How many molecules are present in 1 kg mole of a substance? View Solution How many molecules are present in one gram molecular mass of a substance ?
If, for instance, the solution contains 100 g of potassium chloride — 100 ÷ 74.55 = 1.32 moles. Step 3 Divide the number of moles by the volume of solution in liters (L). If, for instance, the solution is 1.5 L — 1.32 ÷ 1.5 = 0.88. This is the solution's particle ...
(in liters). The prefix "milli-" indicates "1 thousandth," that is, the magnitude of 0.001 (see Resources). Hence, 1 mole is equal to 1 millimoles multiplied by 1,000. As an example, calculate concentration in millimolars if 0.5 grams of sodium hydroxide (NaOH) were dissolved in 500...
You know what your cholesterol levels are, but what do they mean? In the U.S., the numbers are measured by milligrams (mg) and deciliters (dL). The lab looks at how many milligrams of cholesterol are in 1 deciliter of blood, and they come up with a number of mg/dL. ...
moles of water in one drop = 0.002775 moles Using Avogrado's Number Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there...
