59. A pycnometer is a device used to determine density. It weighs 20.455 g empty and 31.486 g when filled with
water (d = 1.000 g/cm'). Pieces of an alloy are put into
the empty, dry pycnometer. The mass of the alloy and
Pycnlometer is 28.695 g. Water is added to the alloy to
exactly fill the pycnometer. The mass of the pycnometer.
water, and alloy is 38.689 g. What is the density of the
allov?

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.
