Answer to: If I have 50 mL of lead (II) nitrate, calculate how many moles are in 1 mL of the substance. By signing up, you'll get thousands of...
How many milliequivalents per liter (mEq/L) are 700 mg KCL in 900 mL solution? Equivalent Per Litre of Potassium Chloride Solution: Equivalent mass is defined as the number of parts by mass of a substance that can combine/displace 1.008 parts by mass of hydrogen/8.0 pa...
How many milliliters of ethanol are needed to prepare 250 mL of a 15.0% (v/v) solution? A) 15.0 mL B) 37.5 mL C) 88 mL D) 8.8 mL 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 ...
This makes the new number 1. 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...
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...
From 200 mg of CO(2), 10^(21) molecules are removed. How many grams and moles of CO(2) are left.
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 ...
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) ...
The number 7 for a cholesterol level would not be a measurement in mg/dL, used in the U.S., but it may be in a measurement used in other countries. Canada, for example, uses millimoles per liter, or mmol/L, for cholesterol tests. 7 mmol/L is a very high LDL level....
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...
