1) B+3 is ok. The exercise already put B+3. What

-------------------------------------------------------------------------------------------------------------------

2) Ge is a neutral atom because it doesn't have any charge.

Germanium has 32 electrons and 32 protons because its atomic number is 32.

Be careful with that.

Neutral atoms have the same numbers of electrons and protons.

How many grams of Na2SO4 can be produced from 423.67 g of NaCl?
san4es73 [151]

Mass of  Na2SO4= 514.18 grams

<h3>Further explanation</h3>

Given

423.67 g of NaCl

Required

mass of  Na2SO4

Solution

Reaction

2NaCl + H2SO4 → Na2SO4 + 2HCl

mol NaCl :

= 423.67 g : 58.5 g/mol

= 7.24

From the equation, mol Na2SO4 :

= 1/2 x mol NaCl

= 1/2 x 7.24

= 3.62

Mass  Na2SO4 :

= 3.62 mol x 142,04 g/mol

= 514.18 grams

What is the mass of 3.0 x 10^23 atoms of neon
kari74 [83]
Molar mass neon = <span>20.1797 g/mol

20.1797 g ---------- 6.02x10</span>²³ atoms
         ? g ------------ 3.0 x 10²³ atoms

mass = 3.0 x 10²³ *  <span>20.1797 / 6.02 x 10</span>²³

mass = 6.054x10²⁴ / 6.02 x 10²³

mass = 10.05 g

hope this helps!

If 16.8 mL of the analyte H2C2O4 (oxalic acid) is titrated with 0.501 M KOH to 13.54 mL, determine the mass of the analyte.​
Neko [114]

Answer:

Mass of Analyte H2C2O4 = 18.18 grams

Explanation:

The balanced equation is:

H_{2}C_{2}O_{4}+2KOH\rightarrow K_{2}C_{2})_{4}+H_{2}O

The Molarity of Oxalic acid needed can be determined using:M_{1}V_{1}=M_{2}V_{2}

Here M1 = Molarity of Oxalic acid

V1 = Volume of oxalic acid

M2 = Molarity of KOH and V2 = Volume of KOH

M1 = ? , V1 = 16.8 mL , M2 = 0.501 M   ,  V2 = 13.54 mL

Put the values and solve for M2,

M_{1}V_{1}=M_{2}V_{2}

2\times M_{1}(16.8)=0.501\times 13.54

We are multiplying by 2 because , 1 H2C2O4 needs 2 KOH

M_{1}=\frac{0.501\times 13.54}{2\times 16.8}

M_{1}=0.202M

Hence Molarity of H2C2O4 =

0.202 M

Molar mass = H2C2O4 = 2x1 +2x12 + 4x16

= 2+24+64 =  90 gram

Mole =molarity\times Molar\ mass

Moles=0.202\times 90

18.18 gram
