Question

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

Answer 1

The ratios would remain the same for both elements, so it would be 1.5 times the mass of sodium in 100 grams.
1.5 * 39.34 grams Na = 59.01 grams Na

Answer 2

59.01 grams is the mass of sodium would make up a 150-gram sample of sodium chloride.

Step-by-step explanation:

Mass of sodium in 100 grams of NaCl contains = 39.34 g

Mass of sodium in 1 grams of NaCl =
`(39.34 g)/(100 )=0.3934 g`

Mass of sodium in 150 grams of NaCl:

`150 * 0.3934 g=59.01 g`

59.01 grams is the mass of sodium would make up a 150-gram sample of sodium chloride.
