What is the mass in grams of 0.7350 moles of sodium?
Alik [6]

Answer:

Explanation:

1 mol of sodium = 23 grams (use the number on your periodic table).

0.7350 mol sodium = x

Cross multiply

1*x = 0.7350 * 23

x = 16.905

You will get slightly less than this, depending on your periodic table. But the method will be the same.

When an object is lifted 6 meters off the ground, it gains a certain amount of potential energy. If the same object is lifted 18
AlexFokin [52]

Answer:

The answer to your question is the letter C. three times as much

Explanation:

Data

First step = 6 m

Second step = 18 m

Potential energy is the energy stored that depends on its position.

Formula

Pe = mgh

m = mass; g = gravity; h = height

Potential energy of the first step

        Pe1 = 6mg

Potential energy of the second step

        Pe2 = 18mg

-Divide the Pe2 by the Pe1

        Pe2/Pe1 = 18mg/6mg

                       = 3
