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

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
