Answer:
0.5077 moles
Explanation:
Data Given:
Moles = n = <u>???</u>
Temperature = T = 300 K
Pressure = P = 380 mmHg = 0.50 atm
Volume = V = 25 L
Formula Used:
Let's assume that the hydrogen gas in balloon is acting as an Ideal gas, the according to Ideal Gas Equation,
P V = n R T
where; R = Universal Gas Constant = 0.082057 atm.L.mol⁻¹.K⁻¹
Solving Equation for n,
n = P V / RT
Putting Values,
n = (0.50 atm × 25 L) / (0.082057 atm.L.mol⁻¹.K⁻¹ × 300 K)
n = 0.5077 moles
Total weight = 1 + 35.45 + 3 * 16 = 84.45
H = 1 / 84.45 * 100% = 1.18%
Cl = 35.45 / 84.45 * 100% = 41.98%
O = 48 / 84.45 * 100% = 56.84%
Answer:
Improved water supply and sanitation and improved water resources management boost countries' economic growth and contributes greatly to poverty eradication. ... National economies are more resilient to rainfall variability, and economic growth is boosted when water storage capacity is improved
Explanation:
Answer:
3.74 atmospheres
Explanation:
If the temperature is constant, then the formula is
V*P = V1 * P1
V = 22.6 L
P = 1.67 atm
V1 = 10.0 L
P1 = ??
=============
22.6 * 1.67 = 10 * P1
37.742 = 10 * P1
37.742/10 = P1
P1 = 3.742
Note there are 3 sig digs in each given, so the answer should be
P1 = 3.74 atmospheres
