What is the concentration of a 2500 milliliter solution that contains 7.5 moles of CaCO3? (Hint: there are 1000 milliliters (mL) in 1 liter (L) )

M = 3.0 M.

Explanation:

Hello there!

In this case, according to the definition of molarity, it turns out possible for us to calculate the required molar concentration of the given volume of solution and moles of solvent by knowing they are divided as follows:

However, since the volume is in liters, we first convert the 2500 mL to L and then calculate the resulting molarity as shown below:

Whereas M stands for molar units of mol/L.

Regards!

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer would be c
