D Because yes steps by step explanation
She should make soup. When you are way above sea level, the atmospheric pressure decreases. Boiling starts when the vapor pressure of the liquid is the same with the atmospheric pressure. This would mean that water boils at a much lower temperature than the usual 100deg C. So it would take longer for the components in the soup to cook compared to when it is cooked on the foot of the mountain.
M2= 0.35M
Formula: M1 • V1 = M2 • V2
1) 25.0mL • .500M = 35.5mL • (x)
2) 12.5 = 35.5 • (x)
3) 12.5/35.5 = x
4) 0.35211 = x = M2
Hope this helps!
Answer: -2.13%
Explanation:
I will assume that the correct time is 94 seconds, since it is stated as a fact. The measured time of 92 seconds is -2 seonds from the actual. That gives a percent error of:
[(Measured-Actual)/Actual] or (-2/94) or -2.13%
