Answer:

Lead to Sulfur = 2 : 1

Explanation:

Given

Represent lead with L and Sulfur with S

L1 = 6.46g for S1 = 1 g

L2= 3.23g for S2 = 1 g

Required

Determine the simple whole number ratio of L to S

Divide L1 by L2

L = L1/L2

L = 6.46g/3.23g

L = 2

Divide S1 by S2

S = 1g/1g

S = 1

Represent L and S as a ratio:

L : S = 2 : 1

Hence, the required ratio of Lead to Sulfur is 2 to 1

1. Calculate the molarity of a sugar solution if 4 liters of the solution contains 8 moles of sugar
klio [65]

Answer:

The molarity of a sugar solution is 2 M.

Explanation:

Molarity is a concentration measure that expresses the moles of solute per liter of solution. In this case it is calculated with the simple rule of three:

4 L of solution--------8 moles of sugar

1 L of solution ------x= (1 L of solution x 8 moles of sugar)/4 L of solution

x=2 moles of sugar---> <em>The solution is 2M</em>

Leona [35]

Answer:

5.5moles

Explanation:

CaC2 + 2H2O —> Ca(OH)2 + C2H2

From the equation, the following were observed:

1mole of CaC2 reacted to produced 1mol of C2H2.

Therefore, 5.5moles of CaC2 will also produce 5.5moles of C2H2
