Is the continental crust less dense or more dense ?

2 answers:

8 0

It is less dense than the material of the Earth's mantle and thus "floats" on top of it. Continental crust is also less dense than oceanic crust, though it is considerably thicker; mostly 35 to 40 km versus the average oceanic thickness of around 7-10 km.

I looked this up but hope it helps!

The pH of a solution is measured eight times by one operator using the same instrument. She obtains the following data: 7.15, 7.

sergiy2304 [10]

Answer:

7.186

Explanation:

The mean is the average of some given data from a sample point.

To calculate the mean, we use the formula below:

Mean = ∑fx/∑f

Where f = frequency

x = sample data

From the given pH of the solutions, we can form a table:

x f fx

7.15 1 7.15

7.16 1 7.16

7.18 1 7.18

7.19 1 7.19

7.20 3 21.6

7.21 1 7.21

Now ∑fx = 7.15 +7.16 +7.18 + 7.19 + 7.20 + 7.21 = 57.49

∑f = 1 + 1 + 1 + 1 + 3 + 1 = 8

The mean = $\frac{57.49}{8}$ = 7.18625 = 7.186

eduard

Standard Molar Volume is the volume occupied by one mole of any gas at STP. Remember that "STP" is Standard Temperature and Pressure. Standard temperature is 0 &176:C or 273 K. Standard pressure is 1 atmosphere or 760 mm Hg (also called "torr"). 1 mole of any gas at STP occupies 22.4 liters of volume.
