Question

The mass of sodium in 5.85g of Nacl

Answer 1

Answer : The mass of sodium in 5.85 grams of NaCl are 2.3 grams.

Explanation : Given,

Mass of NaCl = 5.85 g

Molar mass of NaCl = 58.5 g/mole

Molar mass of Na = 23 g/mole

Now we have to determine the mass of sodium.

As, 58.5 grams of NaCl contains 23 grams of sodium

So, 5.85 grams of NaCl contains $\frac{5.85}{58.5}\times 23=2.3$ grams of sodium

Therefore, the mass of sodium in 5.85 grams of NaCl are 2.3 grams.

Answer 2

Answer:

molar mass of nacl = 23 + 35.5= 58.5

M of Na = 23 g

so = 5.85/58.5×23=2.3g
