<u>Answer:</u> The density of substance is
<u>Explanation:</u>
To calculate density of a substance, we use the equation:
We are given:
Mass of substance = 61.6 g
Volume of substance =
Putting values in above equation, we get:
Hence, the density of substance is
PV = nRT
P is pressure, V is volume, n is number of moles, R is the gas constant, T is temperature in K
(2.85 atm)(12.5 L) = (n)(.08206)(27 C + 273)
n = 1.45 moles x 35.45 grams / mol Cl2 = 51.3 grams
Recognizing the Structure of the Periodic Table. Read the periodic table from top left to bottom right. The elements are ordered by their atomic numbers, which increase as you move across and down the periodic table. The atomic number is how many protons the element's atom possesses.
Answer:
International System of Units
Definition: A system of physical units ( SI units ) based on the metre, kilogram, second, ampere, kelvin, candela, and mole, together with a set of prefixes to indicate multiplication or division by a power of ten.
Hope this helps!
An atom contains protons, neutrons and electrons.
Protons have a positive charge (+1).
Neutrons have no charge (0)
Electrons have a negative charge (-1)
The number of protons and electrons is always the same and so the charges add up to make 0. Therefore there is no overall charge on atoms.
