the mass in grams of 1.00 x 10^23 molecules of N2 is 4.648 g
<u><em>calculation</em></u>
Step 1: use the Avogadro's constant to determine the moles of N2
According to Avogadro's law 1 mole = 6.02 x 10 ^23 molecules
? moles = 1.00 x 10 ^23 molecules
<em>by cross multiplication</em>
= (1 mole x 1.00 x10^23 molecules) / ( 6.02 x 10^23 molecules)
=0.166 moles of N2
Step 2 : find mass of N2
Mass = moles x molar mass
From periodic table the molar mass of N2 = 14 x2 = 28 g/mol
mass = 0.166 moles x 28 g/mol = 4.648 g
100000N/m²
Explanation:
Given parameters:
Weight of the box = 120N
Area of the box = 12cm²
Unknown:
Pressure of the box on the floor = ?
Solution:
Pressure is the force exerted by a body per unit area:
Pressure = 
We need to convert the area into m² from cm²
10000cm² = 1m²
12cm² = 
= 0.0012m²
Pressure = 
= 100000N/m²

Answer:
five electrons
Bromine (Z=35), which has 35 electrons, can be found in Period 4, Group VII of the periodic table. Since bromine has 7 valence electrons, the 4s orbital will be completely filled with 2 electrons, and the remaining five electrons will occupy the 4p orbital
Answer: Check explanation please.
Explanation:
Before diving into the question,let us consider some important facts and definitions.
WHAT IS OSMOLARITY? Osmolarity is the number of OSMOLES of solute per litre of the solution. The unit of osmolary is OSMOLE. Nowadays, osmolarity has become a term used in the past, now osmolarity is called osmotic concentration.
OSMOLARITY can be calculated using; Σ(osmotic coefficient × number of ion × the solute molar concentration).
BACK TO THE QUESTION; ALBUMIN is a PROTEIN. Protein is a large molecule and it contributes an insignificant amount to osmolarity(around 0.6 Mosmole/litre).
Also, if we have the osmotic coefficient to be between zero and one, there is going to be great DISSOCIATION.
