CHEM 1110 FINAL EXAM
density formula -d = m/v m = mass
v = volume
temp conversions -K = C + 273
C = 5/9 (F - 32)
F = (C x 9/5) + 32
average atomic mass formula -(mass A)(% abundance) + (mass B)(% abundance)
molecular mass formula -(mass A)(# of atoms A) + (mass B)(# of atoms B)
mass of element formula -(mass of element in sample / total mass of sample) * 100
molarity with moles formula -M = n/v
M = molarity
n = moles of solute
v = liters of solution
molarity with mass formula -(M)(m)(v) = g M = molarity
m = mass
v = liters of solution g = grams
initial and final molarity with volume formula -M1V1 = M2V2
M = molarity
V = volume
specific heat capacity formula -q = mc∆T
q = heat energy
m = mass
c = specific heat capacity ∆T = change in temp.
ideal gas law formula -PV = nRT
P = pressure (atm)
V = volume (L)
n = moles
R = gas constant (0.08206)
T = temperature (K)
initial and final V and P formula -P1V1 = P2V2
change in energy formula -∆ 𝐸 = 𝑞 + 𝑤
∆𝐸 = change in energy 𝑞 = heat
