Answer:

<em>Recall the following terms which is,</em>

<em> KHP is Potassium hydrogen phthalate</em>

<em>NaOH is Sodium Hydroxide </em>

<em>NaKP is molar mass</em>

<em>H20 is water</em>

Explanation:

<em>KHP + NaOH = NaKP + H2O </em>

<em>moles of KHP = 0.3480g / 204.22 g·mol−1 = .001704 </em>

<em>these will react with the same number of moles of NaOH according to the equation  </em>

<em>these are in 0.03207 L of solution </em>

<em> The  molarity of the NaOH solution = 0.001704 mol / 0.03207 L = 0.0531 M </em>

<em>the water takes no part in the reaction and the quantity can be ignored </em>

The mass of a deuterium nucleus 21H is less than its components masses. Calculate the mass defect.________ amu
Inessa [10]

Answer:

The mass defect of a deuterium nucleus is 0.001848 amu.

Explanation:

The deuterium is:

^{A}_{Z}X \rightarrow ^{2}_{1}H  

The mass defect can be calculated by using the following equation:

\Delta m = [Zm_{p} + (A - Z)m_{n}] - m_{a}

Where:

Z: is the number of protons = 1

A: is the mass number = 2      

m_{p}: is the proton's mass = 1.00728 amu  

m_{n}: is the neutron's mass = 1.00867 amu

m_{a}: is the mass of deuterium = 2.01410178 amu

Then, the mass defect is:

\Delta m = [1.00728 amu + (2- 1)1.00867 amu] - 2.01410178 amu = 0.001848 amu

Therefore, the mass defect of a deuterium nucleus is 0.001848 amu.

I hope it helps you!

krok68 [10]

Answer:

30.8 g of water are produced

Explanation:

First of all we need the equation for the production of water:

2H₂ + O₂ → 2H₂O

2 moles of hydrogen react with 1 mol of oxygen in order to produce 2 moles of water.

As we assume, the oxygen in excess, we determine the moles of H₂.

1.03ₓ10²⁴ molecules . 1 mol/ 6.02ₓ10²³ molecules = 1.71 moles

Ratio is 2:2, so 1.71 moles will produce 1.71 moles of water

Let's convert the moles to mass: 1.71 mol . 18g / 1mol = 30.8 g of water are produced
