What is the molarity of 2.34 mol of calcium carbonate in 1860 ml of solution?
a. 0.79 mol/l
b. 1.26 mol/l
c. 2.34 mol/l
d. 4.35 mol/l

option b= 1.26  mol/L

Explanation:

Given data:

moles = 2.34 mol

volume = 1860 mL

Solution:

molarity = moles of solute/ volume in L

First of all we will convert the mL in L,

1860 mL / 1000 = 1.86 L

now we will put the values in formula,

molarity = 2.34 mol / 1.86 L

molarity = 1.26  mol/L

did anyone actually do this? like if anyone has submitted this i rly need .

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
