A local orchard sells bags of red apples by the dozen. The packaging department of the orchard determines the mass of each dozen batch of
red apples before bagging them. The bag is then labeled with the mass of
the apples. Observe the mass of the dozen red apples shown on the scale.
Based upon this mass, what would the mass of 7 red apples be in
kilograms? Assume that each of the dozen apples on the scale has the
same mass. Answer is rounded to one place after the decimal. 0.5 kg
2.00 kg

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
