Hello!
Given the density of mercury being 13.57 g/mL, and the mass of 52 kilograms, we need to find the volume.
To find the volume, we need to divide mass by density (V = m/d).
Notice that you are given 52 kilograms, but not grams. To convert kilograms to grams, you need to multiply it by 1000.
52 x 1000 = 52000 grams
With the correct measurements, we can find the volume.
V = 52000 grams / 13.56 grams/milliliter
V ≈ 3834.80826
Therefore, the volume of the mercury is about 3,834.81 mL.
Answer: the answer for this question is in the pic
Explanation:
Answer:
The Symbols of elements is given by :
IUPAC : International Union Of Pure and Applied Chemistry .
Its is the Universally recognuised organisation which works on Chemical nomenclature and terminology.
Explanation:
According to IUPAC the elements are named according to mythological concept of country ,mineral , place , property and scientist.
Ex:Copper name comes from the old english word Cyprus.
Rules of Naming elements :
1. The first Alphabet of the element is always Capital.Example:-
Sodium : Na not ''na'
2. The second alphabet is always small .Example
Sodium : Na not ''nA' or NA
3.For most of the elements ,The symbol of the element comes from the <u>first two words.</u>
Example : Hydrogen : H
Helium : He
Copper : Cu
Rules for naming elements having mass> 100
1. The names are derived directly from the atomic number .
Ex : 0 = nil 1= un 2=bi 3=tri
2. The name always ends with ''ium''
For example :
102 = Unnilbium

Answer:
P₂ ≅ 100 atm (1 sig. fig. based on the given value of P₁ = 90 atm)
Explanation:
Given:
P₁ = 90 atm P₂ = ?
V₁ = 18 Liters(L) L₂ = 12 Liters(L)
=> decrease volume => increase pressure
=> volume ratio that will increase 90 atm is (18L/12L)
T₁ = 272 Kelvin(K) T₂ = 274 Kelvin(K)
=> increase temperature => increase pressure
=> temperature ratio that will increase 90 atm is (274K/272K)
n₁ = moles = constant n₂ = n₁ = constant
P₂ = 90 atm x (18L/12L) x (274K/272K) = 135.9926471 atm (calculator)
By rule of sig. figs., the final answer should be rounded to an accuracy equal to the 'measured' data value having the least number of sig. figs. This means P₂ ≅ 100 atm based on the given value of P₁ = 90 atm.
