Which task most likely involves a calculation that uses moles? measuring a sugar sample on a balance counting the number of jellybeans in a jar determining the number of atoms in a jar of liquid finding the rate of expansion of a gas-filled balloon

Answer is: determining the number of atoms in a jar of liquid.

The mole is the unit (with the unit symbol: mol) of measurement for amount of substance. One mole is equal to 6.022·10²³.

1) For measuring a sugar sample grams or kilograms are used.

2) Number of jellybeans is small comparing to mole.

3) For number of atoms, we use mole, because that is very big number.

4) For the rate of expansion speed (m/s or km/s) are used.

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.
