To find the number of molecules in 67.9 g of nitrogen (N), you first need to convert the mass (in grams) to moles using the molar mass of nitrogen (28.02 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules.
26.3 g of calcium hydroxide contain 2,054 molecules.
32 g SO2 x 1 mole SO2/96 g x 6.02x10^23 molecules/mole = 2.0x10^23 molecules
The answer is 1,57.10e27 molecules.
1,4.10e23 molecules
The answer is 1,357.10 ex.23 molecules.
n = gmol = N molecules / N Avogadro n = ( 2.4 x 10^23 molecules ) / ( 6.022 x 10^23 molecules per gmol ) n = 0.3985 gmol m = ( n ) ( M ) m = ( 0.3985 ) ( 141.94 g per gmol ) = 56.6 g <----------------------
To determine the number of molecules in a sample, you need to know the molar mass of the compound. For dimethylmercury, the molar mass is approximately 230.6 g/mol. You can then use the formula n = m/M, where n is the number of moles, m is the mass of the sample, and M is the molar mass, to calculate the number of molecules in the sample.
22.0 g of silver chloride contain 0,918.10e23 molecules.
26.3 g of calcium hydroxide contain 2,054 molecules.
ng = n*g so there are n gs in ng
Anywhere from about 250 calories (12 g of fat) to 679 calories (36 g of fat, 9 or more of which are saturated) depending on the size and the ingredients.
32 g SO2 x 1 mole SO2/96 g x 6.02x10^23 molecules/mole = 2.0x10^23 molecules
The answer is 1,57.10e27 molecules.
1,4.10e23 molecules
