How many lungs does the human body have? Define stroke volume. What is the renal corpuscle? Explain how you would make 750 mL of a 1.35 M KOH solution. What test indicates too much urea in the blood? a. How many moles of NaCl are in 58.5 g NaCl? b. Explain how to make 1L of ...
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 are in a drop of water, which we determined contains 0.002775 moles:...
But the units are no longer moles/L, but rather millimoles/L or mmol/L. These units are called millimolar or mM. While in many cases scientists prefer to talk about concentration in terms of molarity, it can sometimes be more useful to talk about mass per liter solvent. For example, ...
What is the molarity of an HCl solution if 25.0 mL of this solution required 17.80 mL of 0.108 M NaOH to reach the end point in a titration? If 3.50 mL of vinegar needs 45.0 mL of 0.150 M NaOH to reach the equivalence point in a titration, ...
If there are 5 liters of a 3 M solution, how many moles does the solution contain? What is the maximum number of kids a woman can give birth to? Provide evidence. Assume that one strawberry with 3x10^9 cells weighs 16g and that 95% of that weight is water. How much does th...
mL:milliliter mmol/L:millimoles per liter ng/mL:nanograms per milliliter pg (picograms):one-trillionth of a gram People worried about their health can also use the freeAda appto carry out a symptom assessment. Or find out more about how oursymptom checkerworks before you try it for you...
First,how many moles of NaOH were put into the solution?We can find this by multiplying the total volume of NaOH solution by its molarity: (0.02052 L NaOH) x (0.173 mol NaOH / 1 L NaOH) = 3.55 x 10-3mol A total of 3.55 x 10-3moles of NaOH were put into the solution.Since th...
1. Molarity (M): moles of solute/liters of solution or moles/L (mol/L) 2. w/v (g/mL): weight in grams of solute/milliliters of solute 3. w/w: weight in grams of solute/weight in grams of solution (g/g) 4. v/v: volume of solute/volume of solution (L/L) ...
M = moles / liter Example: What is the molarity of a solution of 6 grams of NaCl (~1 teaspoon of table salt) dissolved in 500 milliliters of water? First, convert grams of NaCl to moles of NaCl. From the periodic table: Na = 23.0 g/mol ...
