Learn how to convert the number of grams of a molecule to the number of moles of the molecule with examples below. This type of conversion problem mainly arises when you are given (or must measure) the mass of a sample in grams and then need to work a ratio or balanced equation problem...
How do you do stoichiometry with molarity? How can moles be converted to grams? Define what are moles? How do you do mass to mole stoichiometry? How do you set up a stoichiometry problem? How to convert pounds to grams with a formula ...
What is the molarity of the solution when 300 mL of a 0.400 M solution is diluted to 800 mL? How to convert kg to mg with a formula How would you calculate the volume, in cubic centimeters, of 86 mass ounces of copper (density = 8.98 g/mL). ...
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 know the mass in grams of a mole of cholesterol. This quantity is also known as the molecular ...
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

Explain the concept of molarity and how to calculate it. Calculate the mass in grams 2.6 \times 10^{22} SO_2 molecules. Express your answer using two significant figures. Convert 8.70 um (micrometer)/s to km/hr using 3 significant figures. ...
First, you will need to find the number of moles you need for this solution. To do this, you will need to make use of the desired molarity and the volume of desired solution. (1mol1L)(1L)=1mol This calculation means that you need one mole of salt. Now, you need to use the mola...
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 Cl = 35.5 g/mol ...
Example 2: If you want to make 2 L of 70 actone you would mix 0.70 ml/ml x 2000 ml = 1400 ml acetone with 600 ml water. To convert from solution to molarity, multiply the solution by 10 to express the percent solution grams/L, then divide by the formula weight. ...
