Two objects of the same size will not have the same mass.

<u>Explanation:</u>

Mass is the amount of the matter present in an object.

If the size and shape differs then the mass in that object will also differ.

For example, if we take 2 balls of the same size namely one plastic ball and other one rubber ball.

Both the balls are of same size, but the mass present in plastic ball is lesser when compared to the rubber ball.

So rubber ball has more mass than the plastic ball, and so it is concluded that two objects of the same size will not always have the same mass.

Answer:

Different objects contain different amounts of matter, even if they are the same size. Therefore, two objects of the same size can have different masses.

How many Al atoms are there in 40.5 g of Al foil? Al:27
andrew-mc [135]

Answer:

c) 9.03 x 10^23

Explanation:

find the molar mass of Al

Al is 27.0 grams

Then use that, to find the number of moles in Aluminum.

Then use Avogadro's number which is 6.02 * 10^23

After that, write all of that down with dimensional analysis.

40.5 g * 1 mol/ 27.0 g of Al  * 6.02 x 10^23 / 1mol

As your final answer, you will get 9.03 * 10^23 atoms with sig figs.

Hope it helped!

If 0.220 molmol of a nonvolatile nonelectrolyte are dissolved in 3.70 molmol of water, what is the vapor pressure PH2OPH2O of th
Masteriza [31]

Answer:

Vapor pressure for solution is 22.4 Torr

Explanation:

P° → Vapor pressure of pure solvent

P' → Vapor pressure of solution

Formula for lowering vapor pressure is: P° - P' = P°  . Xm

Xm is the mole fraction. Let's determine it:

0.220 mol of solute + 3.70 mol of water = 3.92 total moles

Mole fraction for solute → 0.220 / 3.92 = 0.056

23.8 Torr - P' = 23.8 Torr  . 0.056

P' = - ( 23.8 Torr  . 0.056 - 23.8 Torr ) → 22.4 Torr

Write a Claim based in this question: What happens in the atmosphere and how
gregori [183]

Answer:

The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.
