the moles to grams conversion represents the conversion of moles into grams. these measurements are used to determine the number of substances. to convert the moles into grams, multiply the mass of the substance by the molecular weight/ formula weight. in other words, it is the product of ...
Question: Three moles of helium gas (molar mass M=4.00 g/mol) are in a rigid container that keeps the volume of the gas constant.Initially the rms speed of the gas atoms is 800m/s. Give your answers to 3 significant figure...
find the molar mass of the substance. multiply both the values. one mole consists of avogadro number of atoms. if you know the quantity of mole, it can be converted into grams and vice versa. the formula for moles to grams is given by example 1 – calculate the ...
Chemistry Can the amount of moles in a mixture be determined using mass and molar mass? General question: If given the mass (15.0 g) of a mixture of two solids (NaCl + C12H22O11), can I find the amount of moles in the mixture by multiplying (15.0 g)*(mol / mass NaCl + mass C12H2...
The number of moles of solute is given by the ratio of the mass of the solute to the molar mass of the same solute. We can write it as : n=mM Where, n is the number of moles m is the mass of a given solute M is the molar...
