V125BC [204]

Answer:

c. protons and neutrons are found in the nucleus

d. protons and neutrons have approximately the same mass

Explanation:

There are three fundamental particles within an atom which are the protons, neutrons and electrons.

The protons are the positively charged particles within an atom

Neutrons do not carry any charges

Electrons are the negatively charged particles.

Both the protons and neutrons occupy the tiny nucleus at the center of the atom.
The electrons moves round the nucleus through the orbital space.
The mass of the protons and neutrons are similar and are assumed to be approximately the same.

How many moles are contained in 70. milliliters of a 0.167 M solution of p-toluidine hydrochloride? Enter only the number to two

kramer

<u>Answer:</u> The amount of p-toluidine hydrochloride contained is 2.4 moles.

<u>Explanation:</u>

To calculate the number of moles for given molarity, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}$

Molarity of p-toluidine hydrochloride solution = 0.167 M

Volume of solution = 70. mL

Putting values in equation 1, we get:

$0.167=\frac{\text{Moles of p-toluidine hydrochloride}\times 1000}{70}\\\\\text{Moles of p-toluidine hydrochloride}=\frac{(0.167\times 70}{1000}=2.38mol=2.4mol$

Hence, the amount of p-toluidine hydrochloride contained is 2.4 moles.

Calculate the mass of 0.750 mol of the following substance. Na3PO4.

Nookie1986 [14]

Na3 = 23*3 = 69
P = 31
O4 = 16*4 =64
69+ 31+ 64 = 164g/mol
0.75mol = 0.75 * 164 = 123 g
