Dik : V = 10 liter T = 25°C = 298 K , P = 100 atm Dit : m = ? Jwb : P × V = n × R × T n = (P × V) ÷ (R × T) n = (100 × 10) ÷ (0,082 × 298) n = 1000 ÷ 24,436 n = 40,92 mol
m = n × Mr m = 40,92 × (4 × 12 + 1 × 10) = 40,92 × 58 = 2373,36 gram
T = 25°C = 298 K , P = 100 atm
Dit : m = ?
Jwb :
P × V = n × R × T
n = (P × V) ÷ (R × T)
n = (100 × 10) ÷ (0,082 × 298)
n = 1000 ÷ 24,436
n = 40,92 mol
m = n × Mr
m = 40,92 × (4 × 12 + 1 × 10)
= 40,92 × 58
= 2373,36 gram
