Question

M(Zn) = 13 гm (Zn) n (Zn) - ?​

Answer 1

Ответ:

M(Zn)- 65

дальше следуем по формуле:

n=m/M

то есть,мы делим массу (13) на молярную массу цинка(65)

13:65=0,2

Ответ: n(Zn)=0,2

Answer 2

It seems like you're trying to write a chemical equation using the symbol "M(Zn)" for an unknown compound involving zinc (Zn). However, the equation you provided is not clear and lacks some important information.

In a chemical equation, the symbols and coefficients represent the reactants and products involved in a chemical reaction. The "M(Zn)" you mentioned appears to be the formula or symbol for an unknown compound. However, without more context or information about the reaction, it is difficult to determine the specific identity or properties of this compound.

Additionally, the expression "13 гm (Zn) n (Zn)" is unclear and seems to be incomplete. It's important to provide complete information and use correct chemical notation when formulating chemical equations.

If you can provide more details or clarify your question, I'll be happy to help you further.
