Hi;) this is easy i just need someone to explain it btw its not B because i already tried it
Kipish [7]

Answer:

<h2>D</h2>

calculate the molar mass of nickel (iii)oxide to the nearest tenth place. Give both the numerial value and the units
maksim [4K]
Nickel (Ni) has the charge as +3 while oxygen (O) has -2. Hence, the chemical formula for the nickel (iii) oxide is Ni₂O₃. 

molar mass of Ni = 58.69 g/mol
molar mass of O = <span>15.99 g/mol

number of Ni atoms in </span>Ni₂O₃ = 2
Molar mass of Ni in Ni₂O₃ = 2 x 58.69 g/mol = 117.38 g/mol

number of O atoms in Ni₂O₃ = 3
Molar mass of O in Ni₂O₃  = 3 x 15.99 g/mol = 47.97 g/mol


Hence, molar mass of compound = 117.38 g/mol + 47.97 g/mol
                                                          = 165.35 g/mol
                                                          =
<span> 165.4 g/mol</span>

14.2 grams of Na2 so4 is dissolved in water to make a 2.50 L solution.What is molarity of solution?
FrozenT [24]

Answer:

The answer to your question is 0.04 M

Explanation:

Data

mass of Na₂SO₄ = 14.2 g

volume = 2.50 l

Molarity = ?

Process

1.- Calculate the molar mass of Na₂SO₄

Na₂SO₄ = (23 x 2) + (32 x 1) + (16 x 4) = 46 + 32 + 64 = 142 g

2.- Calculate the number of moles of Na₂SO₄

                    142 g of Na₂SO₄ ------------------- 1 mol

                     14.2 g of Na₂SO₄ ------------------  x

                                   x = (14.2 x 1) / 142

                                   x = 0.1 moles

3.- Calculate the molarity

Molarity = moles /volume

-Substitution

Molarity = 0.1 / 2.5

-Result

Molarity = 0.04
