1. (4 pts)

Find the number of moles in a 36.0 g sample of water.

n = \frac{m}{M} = \frac{36.0}{18.0}

2. (5 pts)

Use the ideal gas law to solve for pressure.

P V = n R T \Rightarrow P = \frac{n R T}{V}

3. (6 pts)

Write the rate law for the reaction below.

rate = k [A] [B]^{2}

Sure! Here are some practice questions:

Find the number of moles in a 36.0 g sample of water.
n = m/M = 36.018.0 = 2.00 mol
Use the ideal gas law to solve for pressure.
PV = nRT, so P = nRTV
Write the rate law for the reaction below.
rate = k[A][B]²
