Answer:

Molarity = 3.46 M

Explanation:

Given data:

Percentage of silver nitrate = 40.0%

Density of AgNO₃ = 1.47 g/mL

Molarity of solution = ?

Solution:

40% means out of 100g we have 40 g of AgNO₃ and 60g solvent.

Number of moles of silver nitrate = mass /molar mass

Number of moles = 40 g/ 170 g/mol

Number of moles = 0.235 mol

Volume of solution:

Total mass of solution = 100 g

density = 1.47 g/mL which means there are 1.47 gram into 1 mL.

100 g/1 × 1mL/ 1.47 g × 1 L / 1000 mL

0.068  L

Molarity:

Molarity = number of moles / volume in L

Molarity = 0.235 mol / 0.068  L

Molarity = 3.46 M

How many atoms are in a sample of 175 grams of sodium (Na)? The answer needs to be <br> a x 10^b
ValentinkaMS [17]
Atomic mass Sodium ( Na ) = 22.98 u.m.a

22.98 g ----------------- 6.02x10²³ atoms
175 g ------------------- ?? atoms

175 x ( 6.02x10²³) / 22.98 =

4.58x10²⁴ atoms of Na

hope this helps!

Explain the volume of ideal gasses as related to the molar concept.
horrorfan [7]

Answer:

n = Initial volume/22.4L

Explanation:

The molar concept is simply one that is used to find the Number of moles and explain the relationship it has with avogadro's number, molecular mass, molar mass e.t.c.

Now, in terms of molar mass, number of moles is given by the formula;

n = mass of the sample/molar mass

In terms of avogadro's number, number of moles is;

1 mole = avogadro's number = 6.02 × 10^(23)

Now, when dealing with ideal gases, the molar volume of an ideal gas is 22.4 L.

Now the relationship between this volume and the mole concept is that the number of moles is gotten by dividing the initial volume by this molar volume.

Thus;

n = Initial volume/22.4L
