Calculate: A proportionality is not the same thing as an equation, however. To convert a proportionality into an equation it is necessary to multiply by a mathematical constant. For example, a ∝ b means that a = kb, where k is a constant. When referring to gases, this constant is referred to as R, the ideal gas constant. A. In the space below, rewrite the proportionality you created in question 2 so that the proportionality symbol (∝) is changed to “=” and the right side is multiplied by R.

B. Rearrange your equation to solve for the ideal gas constant: R =

C. You should have gotten an equation equivalent to (R = PV / nT). Pick any set of conditions in the Gismo you would like, and then calculate R. Show your work below.
P= V=
n= T= R=

D. Recalculate R using a completely different set of Gizmo conditions R=

Imagine that you have produced several versions of lactase, each of which differs from normal lactase by a single amino acid. describe a test that could indirectly determine which of the versions significantly alters the three-dimensional shape of the lactase protein.
