How do I convert molar concentration to grams?
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
Some dilute sulfuric acid H2SO4 has a concentration of 4.90g per dm3 what is the concentration in mol per dm3?
98 g per dm3 would be 1 molar - so 49 g would be 0.5 molar , so 4.9 g is 0.05 mol per dm3 or 0.05 mol.dm-3
To find the molar mass of a chemical do you add up all of the atomic masses of the elements in the chemical?
Yes- for example: H2SO4 The molar mass for hydrogen is 1.008 g/mol, for sulfur is 32.07 g/mol, and that of oxygen is 16.00 g/mol. Note that these values may vary slightly depending on the periodic table that you use. To find the molar mass: (2 x 1.008) + 32.07 + (4 x 16.00) = 98.09 g/mol
How are you able to find the concentration of a chemical in water?
The concentration of a chemical in water can be found using various methods such as spectrophotometry, titration, or chromatography. These methods involve measuring the absorbance, volume, or separation of the chemical in water to calculate its concentration. accurate measurements and proper calibration are essential for determining the concentration of a chemical in water.
How to find moles from volume in a chemical reaction?
To find moles from volume in a chemical reaction, you can use the formula: moles volume (in liters) / molar volume (22.4 L/mol at standard conditions). Simply divide the volume of the gas by the molar volume to calculate the number of moles present in the reaction.
How do you find the molar mass of compounds like water?
The molar mass is the mass of one mole of a substance in g/mol. In order to determine the molar mass, you must know the chemical formula and have access to a periodic table. Let's use water as an example. The chemical formula for water is H2O. To find the molar mass, multiply the atomic weight on the periodic table in grams/mol for each element times the subscript for the element, and add the molar masses. H: 2 x 1.00794g/mol = 2.01588g/mol O: 1 x 15.9994g/mol = 15.9994g/mol ------------------------------------------------ Molar mass = 18.0153g/mol
What is the molar concentration of 80 g of glucose dissolved in sufficient water to make 2 L of a solution?
The equation to find molar concentration is C= n/v (concentration= moles/volume). For 80g of glucose, you would first need to find the number of moles; n= m x mm (moles= mass x molar mass). Then you can input that number into the equation C= n/v.
How do I convert molar concentration to grams?
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
How do you find the molar mass of an atom?
To find the molar mass of an atom, you need to add up the atomic masses of all the atoms in its chemical formula. This can be determined from the periodic table. The unit for molar mass is grams per mole.
Some dilute sulfuric acid H2SO4 has a concentration of 4.90g per dm3 what is the concentration in mol per dm3?
98 g per dm3 would be 1 molar - so 49 g would be 0.5 molar , so 4.9 g is 0.05 mol per dm3 or 0.05 mol.dm-3
How do you find moles of a chemical with density and molar mass?
You need also to know the volume or the mass of the sample.
To find the molar mass of a chemical do you add up all of the atomic masses of the elements in the chemical?

What is the concentration of a 450 mL solution that contains 200 grams of FeCl2?
To calculate the concentration, first convert the mass of FeCl2 to moles by dividing by its molar mass. The molar mass of FeCl2 is approximately 126.75 g/mol. Next, divide the number of moles by the volume of the solution in liters (0.45 L) to find the concentration in mol/L.

How do you Find the percent composition of oxygen in each of the following compounds?
To find the percent composition of oxygen in a compound, divide the molar mass of the oxygen in the compound by the molar mass of the entire compound, then multiply by 100 to get the percentage. Repeat this calculation for each compound listed.
What is the percent composition of calcium iodide?
Calcium iodide has the chemical formula CaI2. To find the percent composition, calculate the molar mass of CaI2, then find the molar mass contributed by each element (calcium and iodine). Finally, divide the molar mass contributed by each element by the total molar mass of CaI2 and multiply by 100 to get the percent composition.
