9) 8 ohms
100 volt
Explanation:
using ohms law all through
8) v = 3×15
9) R= 120/15
the last V=100×1
Answer: 3.61 L
Explanation:
To calculate the moles, we use the equation:
2 moles of produce = 3 moles of
0.1 moles of produce = moles of
According to the ideal gas equation:'
P = Pressure of the gas = 1 atm (NTP)
V= Volume of the gas = ?
T= Temperature of the gas = 20°C = (20+273) K = 293 K (NTP)
R= Value of gas constant in in kilopascals = 0.0821 Latm/K mol
Thus volume of oxygen at NTP obtained by decomposing 12.26 g of is 3.61 L
Because they have octet structure
Given the volume % of isopropyl alcohol = 36.0 % (v/v)
36.0 mL of isopropyl alcohol is present in 100 mL solution
Volume of the solution = 675 mL
Calculating the volume of isopropyl alcohol present in 675 mL solution:
Volume of isopropyl alcohol in 675 mL solution = 243 mL
Volume of solute (isopropyl alcohol)+Volume of solvent(water) = Volume of the solution
Volume of water present in the solution = 675 mL - 243 mL =432 mL
