Pure salt is made up of sodium and chloride. Each gram

of salt contains 0.393 g of sodium. About how much

sodium is in 55.7 g of pure salt?

24 g

29 g

9 g

90 g

Answer:

21.8901 g

Step-by-step explanation:

Given that:

1 gram of pure salt contains 0.393 g of sodium

1 gram = 0.393g

Gram of sodium in 55.7g of pure salt will be x

1g = 0.393g

55.7g = x

Cross multiply:

x = 55.7 * 0.393

x = 21.8901

55.7 g of pure salt will contain about 21.8901 g of sodium chloride
