Question

Pure salt is made up of sodium and chloride. Each gram of salt contains 0.393g of sodium. About how much sodium is in 59.8g of pure salt?

a) 14.5g
b) 23.2g
c) 5.9g
d) 2.4g

Answer 1

To find the amount of sodium in 59.8g of pure salt, multiply 59.8 by 0.393, which equals approximately 23.5g of sodium, rounded to the nearest tenth.

Step-by-step explanation:

To find out how much sodium is in 59.8g of pure salt, we multiply the given mass of the salt by the proportion of sodium in each gram of salt. According to the question, each gram of salt contains 0.393g of sodium. Therefore, we calculate the amount of sodium in 59.8g of salt by multiplying:

59.8g of salt × 0.393g of sodium per gram of salt = 23.5014g of sodium

Rounding the result to the nearest tenth, as is typically done in scientific measurement, gives us approximately 23.5g of sodium, which is closest to option (b) 23.2g.
