A student obtains an evaporating dish and determines its mass to be 32.79 grams. After following the procedure 1b in the Separations Lab, the student weighs the evaporating dish again. This time the dish weighs 39.19 grams. What is the mass of salt collected?

Respuesta :

Answer:

6.4 grams

Explanation:

Data provided in the question:

Mass of the evaporating dish = 32.79 grams

Mass of the dish after following the procedure 1b in the separation lab = 39.19 grams

Therefore

The mass of the salt collected will be equal to the difference of the mass measured after and before following the procedure 1b

Thus,

Mass of salt collected =  39.19 grams - 32.79 grams

= 6.4 grams
