Answer:
100.4mL
Explanation:
Using the following formula:
C1V1 = C2V2
Where;
C1 = initial concentration (M)
C2 = final concentration (M)
V1 = initial volume (mL)
V2 = final volume (mL)
According to the information in this question,
C1 = 1.50M
V1 = ?
C2 = 9.65 M
V2 = 15.6 mL
Using C1V1 = C2V2
V1 = C2V2/C1
V1 = (9.65 × 15.6) ÷ 1.5
V1 = 150.54 ÷ 1.5
V1 = 100.36 mL
Approximately, V1 = 100.4mL
Answer:
Option A = 14.19 atm
Explanation:
Given data:
Volume of gas = 2.50 L
Number of moles of gas = 1.35 mol
Temperature of gas = 320 K
Pressure of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will put the values in formula.
P × 2.50 L = 1.35 mol × 0.0821 atm.L/ mol.K× 320
P = 35.467 atm.L/ 2.50 L
P = 14.19 atm
Thus, option A is correct.
Answer:
calcium and gold
