What in the world is this !

The density of gold is 19.3 g/cm3, and the density of iron pyrite is 5.02 g/cm3. What substance do you think you found?

Harrizon [31]

Answer:

Step 1

1 of 2

V = m / D; V (nugget of gold) = 50 g / 5.0 g / cm 3 = 10 cm3; V (nugget of iron pyrite) = 50 g / 19 g / cm3 = 2.63 cm 3

Result

2 of 2

Due to these results you can conclude that nugget of gold which volume is 10 cm3 is bigger than volume of nugget of iron pyrite which is 2.63 cm3.

<h3>What is basic solution?</h3>

An aqueous solution that has more OH-ions than H+ions is referred to be a basic solution. It is an aqueous solution with a pH higher than 7, in other words. Ions are present in basic solutions, which also conduct electricity, color blue on red litmus paper and are slick to the touch.

The scale ranges from zero (the most acidic) to fourteen (the most basic). Pure water has a pH value of 7, as can be seen from the pH scale above. Since it is neither acidic nor basic, this value is thought to be neutral.

Potassium hydroxide (KOH), Sodium hydroxide (NaOH), Caesium hydroxide (CsOH), Strontium hydroxide (Sr(OH)2), and Lithium hydroxide are some typical strong Arrhenius bases.

What is the weight of oxygen in 50gwater

8_murik_8 [283]

To compute the required mass of the element to form the given molecules, we'll use the general formula shown below:

{eq}\displaystyle m_1=\frac{M_1}{M_2}\times m_2 {/eq}, where,

{eq}M_1 {/eq} is the molecular weight of the element.

{eq}M_2 {/eq} is the molecular weight of the given molecule.

{eq}m_2 {/eq} is the mass of the given molecule.
