Answer:
to reduce friction and increase efficiency of the machime
Answer:
30g
Explanation:
According to this question, a sulfur-containing compound is said to contain 15 percent by mass of sulfur. This means that 15% of the total mass of the compound is the mass of sulfur in the compound.
The question further states that there is a total of 200g of the compound containing sulfur, this means that the mass of sulfur can be calculated this:
Mass of sulfur = 15% of 200g
15/100 × 200g
15 × 2
30g
Hence, there are 30g of sulfur in 200g of the sulfur containing compound.

Explanation:
Water vapor in the air reaches its dew point as it cools in the air around the can, forming <em>liquid</em> <em>drops</em> <em>of</em> <em>water</em>. Condensation is the process where water vapor becomes liquid.
Water acts as solvent and it has no effect on the amount of the acid or the titrating agent.
<span>Also, the concentration of the titrating agent must be known exactly, the amount of solvent is less important (the more diluted it is, the more accurate is the titration).</span>
