Answer:

We have 0.0170 moles of butyric acid

Explanation:

Step 1: Data given

Density of butyric acid = 0.959 g/mL

Temperature = 20.0°C

Volume = 1.56 mL = 0.00156 L

Step 2: Calculate mass

Density = mass / volume

mass = density * volume

Mass = 0.959 g/mL * 1.56 mL

Mass = 1.496 grams

Step 3: Calculate Number of moles

Number of moles = mass / molar mass

Number of moles = 1.496 grams / 88.11 g/mol

Number of moles = 0.0170 moles

We have 0.0170 moles of butyric acid

mote1985 [20]

Answer:

In this conditions, the gaswll weight 46.74 g.

Explanation:

The idal gas law states that:

PV = nRT,

P: pressure = 740 mmHg = 0.97 atm

V: volume = 14.5 L

n: number of moles

R: gas constant =0.08205 L.atm/mol.K

T: temperature = 29°C = 302.15K

n = \frac{PV}{RT} \\n = \frac{0.97x14.5}{0.082 x 302.15 } \\n = 0.57 mol

1 mol gas ___ 82 g

0.57 mol gas __ x

x = 46.74 g
