Answer:
Mass = 33.515 g
Explanation:
Given data:
Volume of ammonia = 45.0 L
Temperature = 57.0°C (57 +273 = 330 K)
Pressure = 900 mmHg
Mass of ammonia = ?
Solution:
Formula:
PV = nRT
We will use R = 62.364 (L * mmHg)/(mol * K) because pressure is given in mmHg.
900 mmHg × 45.0 L = n × 62.364L * mmHg/mol * K × 330 K
40500 mmHg.L = n × 20580.12L * mmHg/mol
n= 40500 mmHg.L/ 20580.12L * mmHg/mol
n = 1.9679 mol
Mass of ammonia:
Mass = number of moles × molar mass
Mass = 1.9679 mol × 17.031 g/mol
Mass = 33.515 g
When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.
