4 0

Answer:

c

Explanation:

because when you hold a solid in your hand does it move does it shift no it stays the same so it doesn't take the form of the container it's in cuz that's a liquid.

A chemistry student must write down in her lab notebook the concentration of a solution of sodium hydroxide. The concentration o
taurus [48]

Answer:

The concentration the student should write down in her lab is 2.2 mol/L

Explanation:

Atomic mass of the elements are:

Na: 22.989 u

S: 32.065 u

O: 15.999 u

Molar mass of sodium thiosulfate, Na2S2O3 = (2*22.989 + 2*32.065 + 3*15.999) g/mol = 158.105 g/mol.

Mass of Na2S2O3 taken = (19.440 - 2.2) g = 17.240 g.

For mole(s) of Na2S2O3 = (mass taken)/(molar mass)

= (17.240 g)/(158.105 g/mol) = 0.1090 mole.

Volume of the solution = 50.29 mL = (50.29 mL)*(1 L)/(1000 mL)

= 0.05029 L.

To find the molar concentration of the sodium thiosulfate solution prepared we use the formula:

= (moles of sodium thiosulfate)/(volume of solution in L)

= (0.1090 mole)/(0.05029 L)

= 2.1674 mol/L

How many molecules of H2O are there in 1.0 g of H2O?
NISA [10]
Molar mass H₂O = 18.0 g/mol

number of moles :

1.0 / 18.0 => 0.055 moles

1 mole -------------- 6.02 x 10²³ molecules
0.055 moles --------  ? molecules

molecules = 0.055 x ( 6.02 x 10²³) / 1

molecules = 3.311x10²² / 1

= 3.311 x 10²² molecules

hope this helps!

Silver had a density of 10.5 grams per cubic centimeter. What is the mass of 4.0 mL of silver?
Likurg_2 [28]

Explanation:

Given parameters:

Density of silver = 10.5g/cm³

Volume of silver given = 4mL

Unknown:

Mass of silver = ?

Solution:

Density of a substance can be expressed as its mass per unit volume

 Density = \frac{mass}{volume}

 we need to convert our volume to cm³ from mL;

   1cm³ = 1mL

So 4mL = 4cm³

input the values in;

   Mass = density x volume = 10.5 x 4 = 42g
