Percentage mass of chlorine is formula:

Percentage mass composition = mass of element * 100%/mass of compound.

Therefore;

HClO3 (gram-formula mass = 84 g/mol)

Percentage mass composition of chlorine = 35 * 100% / 84 = 42%

See full question below.

In which compound is the percent composition by mass of chlorine equal to 42%?

(1) HClO (gram-formula mass = 52 g/mol)

(2) HClO2 (gram-formula mass = 68 g/mol)

When the price is at $42 per keyboard, there is a surplus in the market. At $42, there is a surplus of 300 units of keyboards in the market. The pressure is downward. When demand is low, there is a pressure for the prices to be reduced.

<h3>What is the market situation at $18?</h3>

At $18, there is a shortage of 200 keyboards. The pressure is upwards. Basic demand and supply indicates that when the demand is above the equilibrium point, the pressure for price to increase is high.

It is to be noted that the equilibrium point is the basis for the above rationalization. The equilibrium point is the price-point at which demand equals supply.
