Question

. A solution of 20.91% by weight H2SO4 (MW = 98.0 g/mol) has a specific gravity of 1.150. What
is the normality of this solution? Water is added to dilute this solution to a solution of 3.03% by
weight H2SO4 (SG = 1.020). How were they mixed and what is the normality of the resulting
solution?

Answer 1

Answer:

From tank treads to bike gears to fishing lines, pulleys are used all over the place when it comes to mechanical transmissions. All types of pulley mechanisms consist of some sort of flexible belt (chain, cable, rope, etc.) turning around the circumference of a wheel, and pulleys can be incredibly useful in a variety of situations. In this Instructable I'll go over some basic pulley concepts and interesting mechanisms, and hopefully you'll be able to design your own pulley systems and make stuff like this!
