The relative formula mass of a compound with formula XS0, is 120. Calculate the ralative atomic mass of Y.
[Relative atomic mass: S, 32; 0, 16]

72

Explanation:

Relative atomic mass of YSO = Relative atomic masses of Y + S + O

This implies; Y + 32 + 16 = 120

Y = 120 - 48

Y = 72

Hence, the relative  atomic mass of Y = 72

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.

i believe the answer is a.
