how to find no of g atoms and weight of an element ?
To find the number of moles (n) of an element, you need to know the mass of the sample (m) and its molar mass (M). You can then use the formula:
n = m / M
Once you have the number of moles, you can then use Avogadro's number (6.022 x 10^23) to find the number of atoms (N) using the equation:
N = n * NA
where NA is Avogadro's number.
To find the weight of an element, you can use the formula:
weight = n * M
where n is the number of moles and M is the molar mass of the element.
Therefore, to find the number of grams (g) and the weight of an element, you need to know the mass of the sample and its molar mass.
