8 0

Answer:

-1.06

Explanation:

0.345 has three significant figures since the zero does not represent a significant figure.

So, usign the calculator, we find ln (0.345) = -1.06421086195

Now, the problem says that you need to report your answer to three significant figures.

So, you should take the first three numbers of the answer:

ln (0.345) = -1.06

What mass of co was used up in the reaction with an excess of oxygen gas if 24.7 g of carbon dioxide is formed
sleet_krkn [62]
Balance Chemical Equation of this reaction is,

                                      2 CO  +  O₂   →   2CO₂

Acc. to this reaction,

88 g (2 mole) of CO₂ was produced when  =  56 g (2 mole)of CO was reacted
So, 
24.7 g of CO₂ will be produced by reacting =  X g of CO

Solving for X,

                                    X  =  (56 g × 24.7 g) ÷ 88 g

                                    X  =  2.26 g ÷ 88 g

                                    X  =  0.0257 g of CO

Result:
           
0.0257 g of CO is required to be reacted with excess of O₂ to produce 24.7 g of CO₂.

What is the current in amperes if 1200 na+ ions flow across a cell membrane in 3.5 μs ? the charge on the sodium is the same as
lbvjy [14]
Charge = 1200 * 1.6 * 10^-19 = 1920 * 10^-19 
Time = 3.5 µs = 3.5 * 10^-6 s  
But Current = charge/time = (1920 * 10^-19) / (3.5 * 10^-6) 
So Current becomes 548.5714 * 10^(-19-(-6)) 
So we have 548.5714 * 10^(-19 + 6) = 548.5714 * 10^(-13) 
So we have 5.485714 * 10^(-15)
