The last 3 options are valid in this particular case.
Answer:
6 M
Explanation:
n = m/M
m= 60g
M(NaOH)= 23 + 16 + 1 = 40
n= 60/40 = 1,5 mol
Therefore c = n/ V = 1,5/ 0,250 = 6
Answer:
Graduated cylinders are designed for accurate measurements of liquids with a much smaller error than beakers. They are thinner than a beaker, have many more graduation marks, and are designed to be within 0.5-1% error. ... Therefore, this more precise relative of the beaker is just as critical to almost every laboratory.

Answer:
true
Explanation:
Hotter things have more heat energy than colder things. That's because the atoms or molecules move around faster in hot things (red, right) than they do in cold things (blue, left). ... The more heat you supply, the faster the molecules move and the further apart they get.
