Question

1. the mass of sodium in 11.7g of Nacl is​

Answer 1

Answer:

Since NaCl has a molar mass of 23.0 g/mol + 35.5 g/mol = 58.5 g/mol, we see that we have:

Moles NaCl = (11.7 g)/(58.5 g/mol) = 0.20 mol.

This corresponds to 0.20*23.0 = 4.60g of sodium........

Answer 2

Answer:

Na mass =23

Cl mass =35.5

NaCl mass =58.5

58.5 g of NaCl consists of 23g of Na

11.7 g of NaCl consists of x grams

x=23×11.7/58.5

x=4.6g
