A solution is made by dissolving 17.2 g of ethanol, CH3CH2OH, in enough water to make exactly 500 mL of solution. What is the concentration (molarity) of CH3CH2OH in mol/L

0.748M

Explanation:

Molarity is defined as the ratio between moles of solute (The substance in the lower amount, ethanol) and liters of solution.

To solve the problem we need to convert the mass of ethanol to moles using its molar mass and the mL of solution to liters:

Moles ethanol:

molar mass:

C₂H₆O:

2C = 2*12g/mol = 24g/mol

6H = 6*1g/mol = 6g/mol

O = 16g/mol

Molar mass: 24 + 6 + 16 = 46g/mol

Moles are:

17.2g * (1mol / 46g) = 0.374 moles

Volume of solution:

500mL * (1L / 1000mL) = 0.500L

Molarity:

0.374moles / 0.500L =

elements

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot

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.
