The conversion factor is added to the original given unit so that you can end up with the final unit. Basically, the conversion unit does not change the value because the factor is just equal to 1. You just manipulate the units by cancelling them.

Among the given choices, the fraction which is equal to 1 is 10⁻³ g/ 1 mg, because there are 1,000 mg per 1 g. In reverse, that would be 10⁻³ of a gram.

If z = 4.0 and y = 9.6, what is the value of x?
krok68 [10]

Answer:

The value of x will be "1.4".

Explanation:

The given values are:

y = 9.6

z = 4.0

As we know,

The relation between x, y and z is:

⇒ z = \frac{y}{x}

and,

⇒ x=\frac{y}{z}

On substituting the given values, we get

⇒    =\frac{5.6}{4.0}

⇒    =1.4

Element A has 15 protons. Determine the number of neutrons in its isotope with mass number 33.
bagirrra123 [75]
In an electrically neuteral atom, number of protons = number of electrons = atomic number.
Mass number = neutrons + protons/electrons/atomic number
Therefore,
neutrons = mass number - <span>protons/electrons/atomic number
Neutrons = 33 - 15 = 18

The answer is thus B. But this is the solution and explanation along with it as proof.</span>
