What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? quzket
Ivanshal [37]

The atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.

Carbon is known as a tetravalent compound.

It has four electrons in its outermost shell. It forms a covalent bond with other compounds.

The number of neutrons. = 6

Number of electrons = 6

Number of protons = 6

So the atomic number of the compound is,

The atomic number of an element = Number of protons present in its nucleus

The number of protons given in the compound is 6.

So the atomic number of the compound is also 6.

Carbon has six atomic numbers.

Therefore, the atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.

To know more about electrons, refer to the below link:

E85 fuel is a mixture of 85% ethanol and 15% gasoline by volume. What mass in kilograms of E85 (d = 0.758 g/mL) can be contained
alexandr402 [8]

The answer is: mass is 40.17 kilograms.

d = 0.758 g/mL; density of fuel.

V = 14.0 gal; volume.

A gallon is a unit of volume in both the US customary and imperial systems of measurement. The US gallon is defined as 231 cubic inches (3.785 liters).

1 gal = 3785.41 mL.

V = 14 gal · 3785.41 mL:

V = 52995.74 mL.

m = 52995.74 mL · 0.758 g/mL.

m = 40170.77 g; mass of fuel.

m = 40170.77 g ÷ 1000 g/kg.

m = 40.17 kg.
