Answer:
0.52 mol
Explanation:
Using the general gas equation formula:
PV = nRT
Where;
P = pressure (atm)
V = volume (Liters)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
At STP (standard temperature and pressure), temperature of a gas is 273K, while its pressure is 1 atm
Using PV = nRT
n = PV/RT
n = (1 × 11.74) ÷ (0.0821 × 273)
n = 11.74 ÷ 22.41
n = 0.52 mol
There are 0.52 moles in the basketball
Answer:
2 ?
Explanation:
(Molar mass of S2Cl2 = 135.036 g/mol)
Eq. wt. of S in S2
Cl
2
= 2×35.5
2×32×35.5 =32g
Eq. wt. of S in SCl
2 =
2×35.5
32×35.5 =16g
So, their ratio is 2.
