If something happens<span> to make an </span>atom<span> lose or </span>gain an electron<span> then the </span>atom<span> will no longer be neutral. An </span>atom<span> that </span>gains<span> or loses an </span>electron<span> becomes an ion. If it </span>gains<span> a negative </span>electron<span>, it becomes a negative ion.

Hope this helps</span>

I'm pretty sure it becomes an ion! If an atom gains a negative electron, it becomes an ion.

<u>Answer:</u> The correct option is C) 1.68 mol/L

<u>Explanation:</u>

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

$\text{Molarity of solution}=\frac{\text{Given mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (L)}}$ .....(1)

Given values:

Given mass of $C_6H_{12}O_6$ = 150 g

Molar mass of $C_6H_{12}O_6$ = 180 g/mol

Volume of the solution = 0.50 L

Putting values in equation 1, we get:

$\text{Molarity of solution}=\frac{150}{180\times 0.50}\\\\\text{Molarity of solution}=1.68M$

Hence, the correct option is C) 1.68 mol/L

Calculate the density of unknown substance #1 which has a mass of 15.8 grams and a volume of 20 cm3. *

GenaCL600 [577]

Answer:

$\boxed{\sf Density \ of \ unknown \ substance = 0.79 \ g/cm^3}$

Given:

Mass = 15.8 g

Volume = 20 cm³

To Find:

Density of unknown substance

Explanation:

Formula:

$\boxed{ \bold{Density = \frac{Mass}{Volume}}}$

Substituting value of mass & volume in the formula:

$\sf \implies Density = \frac{15.8}{20} \\ \\ \sf \implies Density = 0.79 \: g/cm^3$

What is the Percent composition of a pure substance that contains 7.22g of nickel, 2.53g of phosphorus and 5.25 g oxygen

emmasim [6.3K]

Answer:

Explanation:

Total mass of substance = 7.22 + 2.53 + 5.25 g

= 15 g

percentage of nickel = 7.22 x 100 / 15

= 48.13

= 48.1 %

percentage of phosphorus = 2.53 x 100 / 15

= 16.87%

= 16.9%

percentage of oxygen = 5.25 x 100 / 15

= 35 %
