Question

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

Answer 1

option b= 1.26 mol/L

Step-by-step 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
