Eduardo dissolved as much salt as he could into a beaker of water. he did not measure the salt as he put it in, but he wanted to know how much salt had dissolved into the water. he weighed the saltwater and the beaker. the total mass of both was 156 g. eduardo gently heated the beaker of saltwater until all the water evaporated, then weighed it again.
the salt and beaker together massed 56 g. when he removed all the salt from the beaker, the beaker weighed 20 g.
how much salt did eduardo dissolve into the water?
Beaker weighs 20g
Therefore salt weighs 56 - 20 = 36g
PS the total mass (156g) is a red herring!
its is correct
for the points and to tell you that the answer above me is correct
Answer is in the file below
Name: Put your name, teachers name, date, and Spheres of Earth Hands on Lab Report.
Objective: To demonstrate nature in a small environment.
Hypothesis: If I kept my terrariums in the dark, then the water level will stay the same.
Procedure: I got a container for my terrarium and put in things that would normally be on Earth like plants, rocks, and water. My terrarium was perfect and looked cool.
Day 1: 3 inches
Soil: present, mostly dry.
Day 2: 2.9 inches
Soil: present, moist
Day 3: 2.5 inches
Soil: present, wet
The water level was similar in both terrariums. Some of the water evaporated each day. There was water dropplets on the lids. The soil was getting wetter as more days passed due to humidity. My hypothesis was correct because less exposure to sunlight decreases evaporation. If I was to repeat the experiment, I would use a darker place and make my observations more accurate. In real life, in caves it is very dark so there is very little humidity.
Soil, water, plants, sunlight, and sediment.
spheres of the earth is a good book so
i need the p
WHAT IS THE LAB!!!
this answer is !
