a. How many moles of NaCl are in 58.5 g NaCl? b. Explain how to make 1L of a 1M NaCl solution. Define the minute volume. What role does ADH play in the final volume of urine? Describe the pH scale a. What does the pH scale measure? b. What is the numerical organization of the...
How many moles of glucose are contained in one liter of 1 M glucose solution? What is a mole, and how do you convert from grams to moles? How does this relate to Avogadro's number? How many moles of copper (II) sulfate do you need to make 3.50 liters of 1.5...
A liter is 10 times more volume than a deciliter, so multiply mg/dl by 10 to get mg/l. Determine the ratio to convert milligrams of cholesterol to millimoles (mmol) of cholesterol. The ratio of milligrams to millimoles is equal to the ratio of grams to moles. You therefore need to ...
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. What are ...
How many milliliters in a liter? Person A takes 8 hours to get to a destination driving 77 mph non-stop. Person B takes 11.5 hours to drive the same distance stopping twice for 15 minutes each time. How many mph was Person B driving?
So, in the present problem, we have M which has units of moles/liter and we have mls which we will convert to liters. Then we will also have to change moles to millimoles (mmole) since that's what the question asks for. I'll do it in individual steps first, and then show you...
To work out molarity, you need to know the total volume of solution as well as the number of moles of solute. Divide the number of moles of solute by the number of liters of solution. For example, if you have 3.4483 moles of table salt in 10 liters of water, work out 3.4483 ÷ ...
from Chapter 15/ Lesson 9 25K The measures of volume in centimeters can be converted to millimeters using a conversion formula. Practice the steps in turning 1 cubic centimeter into milliliters through example problems. Explore our homework questions and answers library ...
Chemists have a variety of means at their disposal to communicate the concentration of chemicals in solution. One common method of describing concentration is to give the moles chemical per liter solution, or the molarity. A mole is a term which stands f
Molarity is measured in moles per liter (mol/L), whereas PPM is a measure of concentration (mass per unit volume) in which the denominator is, as the name of the unit implies, one million times that of the numerator. In standard units, then, 1 PPM translates to 1/1,000th of a gra...
