For example, salt is the solute in a salt water solution, and isopropanol or ethanol is the solute in a rubbing alcohol solution. Before working out moles of solute, you need to understand what a mole is. Molar Mass Calculator Common Compounds Periodic Elements Chemical Formula HCl also ...
Homework Statement This is a question from a chemistry book Two oxides of a metal contain 27.6% and 30% of oxygen respectively. If the formula of the first oxide is MO, find that of the second? 3. The Attempt at a Solution In the first MO, if the total amount is 100g, then O is...
To convert moles to liters, you can reverse the formula: liters (L) =moles (mol)/molarity (M) For example, if you need 8 moles of a substance to carry out a reaction and in your laboratory, you have a 2M solution of that substance, you will need 4 L of the 2M solution to car...

There is also a solution to try the mole fraction calculator instead. FAQs How do I convert from gram to moles? To convert from grams to moles, follow these few simple steps: Measure the mass of your sample in grams. Find the molar mass of the substance you are analyzing. Divide the ...
This is a calculator to convert from mass and molar mass to moles. Moles (measured in mol) is equal to mass divided by molar mass (measured in g/mol). This calculator can be used to find the moles of a solution where mass and molar mass are both known. ...
Determine the number ofmolesof CO2in 454 grams of CO2. Solution First, look up theatomic massesfor carbon and oxygen from theperiodic table. The atomic mass of C is 12.01, and the atomic mass of O is 16.00. The formula mass of CO2is: ...
The number of a mole in a substance is the ratio of given mass and molar mass.Answer and Explanation: A mole of a substance does not depend on the volume of the solution but it depends on the molar mass of the substance. 1 mole of a substance is equal...Become...
