A startup’s customer base doubles every 18 months. Starting with 2,500 users, how many after 4.5 years?

Question and answer

Time = 4.5 years = 54 months Doubling period = 18 months Number of doublings = 54 / 18 = 3 Users after 4.5 years: = 2,500 × (2^3) = 2,500 × 8 = 20,000 users

Time = 4.5 years = 54 months
Doubling period = 18 months
Number of doublings = 54 / 18 = 3
Users after 4.5 years:
= 2,500 × (2^3)
= 2,500 × 8
= 20,000 users

2,500 * 2^3 = 2,500 * 8 = 20,000.
So, after 4.5 years, the startup will have 20,000 users.

Estimate the pH of a 0.05 M acetic acid solution (Ka = 1.8 × 10 ).

Weegy: Given: CH COOH 0.1 M, Ka = 1.8?10 CH COOH H + CH COO Let x = [H ] Ka = x? / (0.1 x) = x? / 0.1 x? = Ka ? 0.1 = 1.8?10 ? 0.1 = 1.8?10 x = (1.8?10 ) = 1.34?10 ? M pH = -log(1.34?10 ?) = 2.87 Answer: pH = 2.87 (More)

C = 0.05
Ka = 1.8e-5
H_conc = (Ka * C)**0.5
pH = -log10(H_conc)
H_conc = (1.8e-5 * 0.05)**0.5
H_conc= 0.0009487
pH = 3.02

mass_glucose = 100 # g
M_glucose = 180.16 # g/mol
M_ethanol = 46.08 # g/mol
moles_glucose = mass_glucose / M_glucose
moles_ethanol = moles_glucose * 2 # C6H12O6 = 2 C2H5OH + 2 CO2
mass_ethanol = moles_ethanol * M_ethanol
moles_glucose = 100 / 180.16
moles_ethanol = moles_glucose * 2
mass_ethanol = 51.1 g

mass_C3H8 = 15 # g
M_C3H8 = 44.1 # g/mol
moles_C3H8 = mass_C3H8 / M_C3H8
moles_O2 = moles_C3H8 * 5 # C3H8 + 5 O2 = 3 CO2 + 4 H2O
mass_O2 = moles_O2 * 32
moles_C3H8 = 15 / 44.1
moles_O2 = moles_C3H8 * 5
mass_O2 = 54.2 g

n_H2 = 2
H_reaction_per_mol = -286 # kJ/mol H2
H_total = n_H2 * H_reaction_per_mol
H_total = 2 * -286
H_total = -572 kJ

mass_NH3_produced = 50
mass_NH3_theoretical = 100
percentage_yield = (mass_NH3_produced / mass_NH3_theoretical) * 100
percentage_yield = (50 / 100) * 100
percentage_yield = 50%
