Conversion of a certain mass of a substance to moles requires knowing the molar mass. Molar mass is given in grams per mole. Dividing the known mass by the molar mass gives the number of moles.
You have to first convert Kilos to grams. 1.42 kilos is 1420 grams. Next you have to find out the molecular weight (can be added up from the periodic table). Now divide grams by molecular weight to get your final answer in moles.
To convert grams to moles, you divide the given mass in grams by the molar mass of the substance in grams per mole, which is obtained from the periodic table. This calculation gives you the number of moles present. Avogadro's number (6.022 x 10^23) is used to convert moles to individual particles or entities like atoms or molecules.
The answer is 902,45 g.
To find the number of molecules of CH3Cl in 101 grams of the substance, you would first convert 101 grams of CH3Cl to moles using its molar mass. Once you have the moles of CH3Cl, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
The chemical formula of hydrated Epsom salt is MgSO4.7H2O. The molar mass is 246,47 grams. 5,2 X 246,47 = 1281,644 grams
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
The answer is 1,54 moles.
Multiply the number of moles by the molecular weight.

The molar mass of a compound is expressed in grams.
To convert moles to pounds, you need to know the molar mass of the substance in grams/mol. Once you have the molar mass, you can convert moles to grams using the formula: moles x molar mass. Finally, you can convert the grams to pounds by dividing by 453.59 grams per pound.
Convert grams of the given reactant to moles using its molar mass. Use the mole ratio from the balanced chemical equation to convert moles of the given reactant to moles of the desired product. Convert moles of the desired product to grams using its molar mass, if needed.
Actually, you can. You can convert grams to moles then moles to meters... or vise versa. usually the place of a mol is 1. unless you are good at chemistry.
No, you do not need to convert grams to moles when using the ideal gas law. The ideal gas law is typically used with moles of gas, but you can directly use grams by adjusting the units of the gas constant accordingly.
To convert moles to grams, you use the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. Therefore, 1.3 moles of calcium would be 1.3 moles x 40.08 g/mol = 52.10 grams of calcium.

To convert grams to atoms, you need to first convert grams of nitrogen to moles using its molar mass (14.01 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, for 2.2 grams of nitrogen: Convert grams to moles: 2.2 g / 14.01 g/mol = 0.157 moles. Convert moles to atoms: 0.157 moles x 6.022 x 10^23 atoms/mol = 9.46 x 10^22 atoms of nitrogen.
