A 100-gram sample of sodium chloride (NaCl) consists of 60.66 g of chlorine and 39.34 g of sodium. What mass of sodium would make up a 150-gram sample of sodium chloride?
89.34 g
39.34 g
59.01 g
64.24 g

The answer is 59.01 g

If a 100-gram sample of NaCl consists of 39.34 g of sodium, a 150-gram sample of NaCl will consist x g of sodium:

100 g : 39.34 g = 150 g : x
x = 39.34 g * 150 g : 100 g
x = 59.01 g

Answer: The mass of sodium making up the given amount of sodium chloride will be 59.01 g.

Explanation:

We are given:

Mass of sodium chloride is 100 g which is made from 39.34 g of sodium and 60.66 g of chlorine.

So, to calculate the mass of sodium which makes up 150 grams of sodium chloride, we use unitary method.

Mass of sodium required will be = [tex]\frac{39.34g}{100g}\times 150g=59.01g[/tex]

Hence, the mass of sodium making up the given amount of sodium chloride will be 59.01 g.
