Question

Найти m(грамм) и n(моль) содержащихся в O2 имея только то что M= 32г/моль, а N(молекул)) 6×10 с степенью 23​

Answer 1

Ответ:

n(O2)=N(O2):Na=(6×10²³):(6×10²³)=1моль

m(O2)=n(O2)×M(O2)=1×32=32грамма

Ответ:32 грамма

Answer 2

Calculating the Mass and Moles of O2

To find the mass (m) in grams and the amount of substance (n) in moles of O2, we can use the given information that M (molar mass) = 32 g/mol and N (number of molecules) = 6 × 10^23.

Step 1: Calculating Moles (n) The number of moles (n) can be calculated using Avogadro's number, which states that 1 mole of any substance contains 6.022 × 10^23 particles.

Using the given information: n = N / Avogadro's number n = 6 × 10^23 / 6.022 × 10^23 n ≈ 0.996 moles

Step 2: Calculating Mass (m) The mass (m) can be calculated using the formula: m = n * M

Using the given information: m = 0.996 moles * 32 g/mol m ≈ 31.872 grams

Therefore, the mass of O2 is approximately 31.872 grams, and the amount of substance is approximately 0.996 moles.
