molarity equals the number of moles divided by the number of liters. unit is molarity, or the solution is ___ molar. the blank is the numeric you get by the division of the moles by liters. I was taught to use dimensional analysis. A mole is 6.02 * 10^23 and you just have to get the unit from liters or whatever you started with to that. I'm sure if you type dimensional analysis into Google it will tell you how to do it because I can't really help you much more without knowing the problem and the units it started in. More simply, you could multiply the concentration by the volume to find the number of moles. e.g. 0.1mol^dm-3 x 0.5L = 0.05M

What is the atomic mass of 25mg?

The atomic mass of a substance is the mass of one mole of that substance. To calculate the atomic mass of 25 mg of a specific element, you would first need to determine the molar mass of that element. You can then use the molar mass to convert the mass of the sample (25 mg) to the number of moles, and then calculate the atomic mass of that amount.


What is the molar mass of a substance with a volume 258 milliliters and a mass of 0.599 g at 0.988 atmospheres and 100 degrees Celsius?

To find the molar mass, you first need to calculate the number of moles of the substance using the ideal gas law equation PV = nRT. Convert the volume to liters (0.258 L) and temperature to Kelvin (373 K). Then calculate the number of moles of the substance. Finally, divide the mass of the substance (0.599 g) by the number of moles to get the molar mass.


How is stiochiometry used to calculate the mass of a substance?

Stoichiometry is used to calculate the mass of a substance by utilizing the relationships between the amounts of reactants and products in a chemical reaction, as defined by the balanced chemical equation. By converting moles of one substance to moles of another using the mole ratios from the equation, we can then apply the molar mass of the desired substance to find its mass. This process allows chemists to predict how much of a substance will be produced or consumed in a reaction, facilitating accurate measurements in laboratory settings.


Moles of As in Na2HAsO4.7H2O?

To find the moles of As in Na2HAsO4.7H2O, you would first calculate the molar mass of Na2HAsO4.7H2O, then divide the molar mass of As by the molar mass of Na2HAsO4.7H2O to find the moles of As.


What would you need to do to calculate molality of 10g of NaCI in 2Kg of water?

To calculate the molality of a solution, you need to divide the moles of the solute (in this case, NaCl) by the mass of the solvent (water) in kilograms. First, convert the mass of NaCl to moles using its molar mass. Then, calculate the molality by dividing the moles of NaCl by the mass of water in kilograms.
