SOLUTION Analyze We are given the number of moles and the name of a substance and asked to calculate the number of grams in the substance. Plan To convert moles to grams, we need the molar mass, which we can calculate using the chemical formula and atomic weights. Solve Because the calciu...
Unit 3 Lesson 2 Practice: Converting liters of gas to liters of gas 49 -- 2:11 App Unit 3 Lesson 1 Practice: Converting Moles to Moles 35 -- 7:10 App Unit 1 Lesson 3 Practice: Converting grams to grams 32 -- 3:12 App Unit 5 Lesson 3 Explanation: Concentration Units 47 -...
Molarity is a unit in chemistry that quantifies the concentration of a solution by measuringmolesof solute per liter of solution. The concept ofmolaritycan be tough to grasp, but with enough practice, you'll be converting mass to moles in no time. Use this example molarity calculation of a...
Re: converting ng/ml into micromoles «Reply #2 on:September 12, 2008, 10:31:25 AM » Honestly, this is HS problem but I won't move the question as it would be a cruel joke. 3.5 ng - how many moles? In general - how do you convert mass to moles?
Likewise, to convert moles to grams, multiply the number of moles by molar mass/1 mole. How many grams are in a mole? The number of grams in a mole, or 'molar mass', is different depending on the element or compound. To find the molar mass of a simple element, look at the ...
$$\text{Molar mass of Carbon}=12.0107 g/mol $$ Step 2:Find the number of moles of the given substance. $$\text{Number of moles} = \text{Weight of the given substance} \times \frac {1}{\text{Molar mass}} $$ Convert moles to atoms by using Avogadro's number. ...

I have dissolved oxygen data that is in units of µmol/liter. I need to convert it to mmol/kilogram. I have been told by someone who knows more about chemistry than I do (but only a little bit more) that I need to know the mass of my sample as well (wh
In summary, the conversation discusses the confusion surrounding converting 1 ml of 10 N NaOH into moles. The significance of 'N' is also questioned. The answer to the number of moles is determined to be 0.01 mol OH. The concept of normality is mentioned and two different definitions are ...
To make biofuels, tiny microbes can be used to break down plant cells. As part of that digestive process, specialized enzymes break down cellulose—a major molecule that makes plant cell walls rigid. Scientists showed that an enzyme, from the bacterial g
