Question

MCs2=152г найти n и N no

Answer 1

N=m/M
n=152/133=1,142 моль
N=1,142*6,022*10^23моль^-1= 6,877*10^23 моль^-1

Answer 2

To find the number of moles (n) and the number of particles (N₀) given the mass (m) of a substance, we need to use the molar mass (M) of the substance. The relationship between these quantities is as follows:

n = m / M N₀ = n * Nₐ

Where: n = number of moles m = mass of the substance (in grams) M = molar mass of the substance (in grams per mole) N₀ = number of particles Nₐ = Avogadro's number (approximately 6.022 x 10^23 particles per mole)

In your case, you provided the mass of the substance (MCs2) as 152g. However, we need to know the molar mass of Cs₂ to proceed further. The molar mass can be determined by summing the atomic masses of the constituent elements.

Please provide the molar mass of Cs₂, and I will calculate n and N₀ for you.
