<u>Answer:</u> The concentration of solution is 0.342 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Mass of solute (Sodium chloride) = 15 g
Molar mass of sodium chloride = 58.5 g/mol
Volume of solution = 750 mL
Putting values in above equation, we get:
Hence, the concentration of solution is 0.342 M
Answer:

Answer:
7.01 mol CH4
Explanation:
STP means standard temperature and pressure, so they are basically telling you that the gas is at 1 atm and 273 K (0 degrees celsius). Now that we have the pressure, volume, and temperature we can use the ideal gas law and solve for n or moles
PV=nRT
n=PV/RT
n=(1)(157)/(0.08206)(273)
n=7.0081 (round to 3 sigfigs)
n=7.01 mol
I think the answer is
B
Hope it helps
